Draganfly Innovations Inc. has released the Draganflyer X4-P, the newest model in their line of amazing, flying UAVs. The notion of safe, stable, and affordable aerial video and photography platforms has been this company’s niche. Featuring phenomenal stability, a patented portable folding airframe design, a stabilized camera mount with vibration isolation, and a boost in flight time, this new Draganflyer is no exception.

The Draganflyer X4-P is exceptionally light weight and portable. The exclusive patented folding airframe fits inside a suitcase-sized military case that is water and crush proof. This combination makes the X4-P “all-in-one-box” system small enough to be transported anywhere at any time.

The design of the Draganflyer X4-P integrates safety and durability into one package. The use of high quality, lightweight carbon fiber parts in the advanced airframe design and the cutting-edge electronic flight stabilization system gives the user the security and piece of mind when operating the X4-P. Other notable features included with the system are two flight batteries (with state-of-the-art integrated protection circuits that provide battery status along with an easy to use battery life gauge), high intensity LED navigation lights for long distance and low-light flying, an onboard flight data recorder which captures all flight data on a removable memory card, and an “auto-landing” feature if the radio link to the helicopter is lost.

Draganflyer X4-P

The Draganflyer X4-P camera mounting system has enhanced vibration protection, which confines the camera from the helicopter, and features an active tilt function to keep the camera level while in flight This combination provides silky smooth and stable video and photos.

Draganfly Innovations has incorporated all the standard features of previous Draganflyer UAV systems. The advanced onboard flight computer system with the SteadyFlight software is the helicopter’s driving force in attaining information from the eleven on-board sensors, making hundreds of calculations per second to produce exceptional flight-handling while delivering an easy-to-control experience for the user.

The custom designed handheld controller offers the user a 2.8” touch screen OLED graphical display for telemetry and flight data (such as GPS position, altitude, heading, bearing, helicopter battery voltage, and more). The controller also features a built-in dual diversity video receiver that takes the streaming, real-time video transmitted from the helicopter and displays it on a pair of video glasses or the wireless video base station.

Draganfly Innovations Inc. designs, develops, and builds these State-of-the-Art systems from the ground up. The development of all hardware and software systems takes place in the company’s development/manufacturing facility. The Draganflyer UAV helicopters are unmatched in performance and simply put, each is a work of art.

There’s been a huge increase in the number of RC helicopters controlled by cell phones and tablets.

Parrot AR Drone

This is one of the higher end cell phone controlled RC helicopters. It works by generating it’s own wifi network that you can connect to with your Android or Apple phone. After you’re connected, you can fly the rc helicopter around and look at a live video feed. The Parrot even has an ultrasound altimeter that tells you how high you’re flying above the ground. The Parrot AR is gyro stabilized, so you can get the hang of flying it in only a few tries.

It has a foam structure around all the rotor blades, so collisions with walls and furniture really aren’t a big deal. The Parrot AR works outside as well – it’s big enough to not get bounced around by light wind too much.

Cheap RC Helicopters without Cameras

If you walk in to Best Buy or Target you’re likely to see boxes of smaller RC helicopters that work with iphones. These are usually fairly simple, only two or three channel RC helicopters. They are sold with a simple interface to your iphone, usually one that plugs in to the headphone jack on the bottom. These ones are usually in the $50 dollar price range.

Building your Own

Building an RC helicopter that you can control by a cellphone or over a network isn’t as hard as it once was. Small computers like the Arduino can control brushless motors and servos, and they also have modules that enable wireless communication. If you build a quad copter airframe and control it over a cell network, you can make a helicopter that works almost anywhere.

This spreadsheet has over 13000 data points for different propellers. Each row contains the following information:

• Propeller Name
• Motor Used
• Gear
• Propeller Diameter
• Propeller Pitch
• Amps, Volts and Watts drawn
• RPM
• RPM as % of Kv * V
• Motor Weight
• Motor and Gearbox weight
• Thrust (in g and oz)
• Grams per Watt
• Pitch Speed

From this data, you can make a more educated choice on which propeller is best for your application. Looking at figures such as the number of grams per watt obtained can help you choose between similar propellers by giving you an estimate of which ones are more efficient in different situations. Depending on if you’re building a quad copter for hovering and aerial photography, or a high performance RC airplane, you can now get an objective picture of the differences between the propellers.

Because simulating how propellers perform in the real world is difficult, testing is necessary to measure their true performance. Before now, finding a unified source of data for many different propellers was difficult.

Here’s some example data, taken for an APC 8×6 E Thin Electric Propeller with a Hacker A20-22L  brushless motor:

If you wanted to know how this propeller performs with this motor as RPM is increased, you could make a plot like this in any spreadsheet program.

Adding a trendline to the data allows you to make a prediction about the thrust this propeller and motor would provide at other RPM values. A simple polynomial fits the measured data well.

Another quantity you might be interested in is the efficiency of the propeller and motor in grams of thrust produced per watt of power used. Here is one such plot.

This one’s really cool - a new coaxial RC helicopter that can fly outdoors, even in the wind! Something about the vertically mounted tail rotor allows it to rapidly compensate for wind gusts and stay stable. Coaxial RC helicopters are usually really stable, but this causes them to do badly in the wind. Somehow, this one manages to overcome that.

Flying in the Wind – Extreme Conditions

Coaxial helicopters are great for learning how to fly, but their inherent stability usually causes them to be very sensitive to the wind. Using the vertically mounted tail rotor and patented technology, the Extreme Flyers X350 overcomes this problem. Not only can it be flown in extremely windy conditions, it’s actually easy to do! Here’s a video to prove it – watch how the wind affects the trees and the flags near the flying helicopter.

There’s even mode to turn off the tail rotor if you’re flying the X350 indoors, which reduces the sensitivity of the controls. Since coaxial RC helicopters don’t have a particular need for a tail rotor, the vertically mounted tail rotor can be used to help stability in high winds.

Great for beginners and Intermediate Pilots

The Extreme Flyers X350 helicopter is great for both beginning and intermediate pilots. The helicopter has enough control to satisfy those wanting to improve their skills and those who are just learning how to fly. Even though the Extreme Flyers X350 RC helicopter has the stability which comes with a coaxial design, the helicopter has enough speed to cover a park in a few seconds flat.

Reviews

This helicopter has attracted a lot of attention on forums – here are a few of the reviews:

• RCGroups.com review
• Modelairplanenews.com review

Finding a unified source for this data is also difficult. A group from the University of Illinois have done static testing on small propellers (less than 5 inches), suitable for building micro quad copters with. The paper is available for download, and the important results are on page 5. The have obtained what is called a “Figure of Merit” (FOM) for each propeller, which is the ratio of the ideal power required to hover to the experimental result. The better the propeller is, the closer this ratio is to one. Working from this, you can do some simple algebra to get the coefficients of thrust and power from their results. This data should help you make a good propeller choice for your RC quad copter project.

Our sources here at RChelicopter.com tell us that this video was shot and put together by the same person who put together this tutorial on how to shoot video like this. The video below is from this tutorial.

The video below shows the Draganflyer X6 being used by the Mesa County’s Sheriffs office in a SWAT training exercise.

These new cutting edge technologies from Draganfly Innovations represent the ultimate in UAV RC Helicopter technology. Draganflys leading edge hand held ground control station incorporates all the features of their already awesome hand held controller with the features of their video base station. You can view live video transmitted from the Draganflyer X6 or the Draganflyer X8 in the palm of your hand while you fly the helicopter. The Draganfly hand held ground control station has an embedded computer running a linux operating system which allows the user to run Draganview software on the 6.3 inch bright day light viewable LCD screen.

Draganfly Innovations has been making big news at the 2010 AUVSI conference in Denver Colorado. For two days in a row they have been written about in AUVSI daily published newspaper Unmanned News. The first article talked about the newly released heavy payload Draganflyer X8, and the second article focused on the exciting new hand held ground control station.

The Denver post has even published an article on the Draganfly X6 being used by the Mesa County Sheriffs department. This article details how the Mesa County Sheriffs department is working with the FAA in order to use the Draganflyer X6 for police operations.

Draganfly Innovations continues to lead the way in UAV RC Helicopter Technology.

Draganfly Innovations has made another UAV helicopter.

The Draganflyer X8 UAV is larger than the X4 and the X6, and it can carry up to 1 kilogram in camera payloads. The X8′s going to offer some more features, such as compatability with DSLR cameras and digital video transmitters. Check out this video (a computer rendering of the X8 in flight with an SLR camera).

One of the major new improvements to the Draganflyer X8 is the inclusion of support for the new IP video camera systems. IP cameras use the same technology your laptop uses to connect to the internet to communicate and transmit video. Basically, the IP cameras form their own network with your computer, allowing you to view the live video feed over the internet. IP cameras support the following features:

• Simultaneous pictures and video – Each IP camera has an internal memory buffer that stores video before it is transmitted. This means that you can take high resolution digital still photos with the IP camera while it is still recording video, allowing you to get exactly the pictures that you need.
• Security and encryption – The IP cameras operate over their own wireless network, which can be encrypted to prevent unauthorized access to the video stream.
• Reduced interference – Digital video is much less susceptible to interference than analog video. Reduced signal strength usually results in a lower frame rate, but not decreased image quality.

IP video cameras will work with the Draganflyer X8 and X6 sometime in the near future, but can’t be used on the smaller X4 due to weight limitations.

Interested in UAV helicopters? You can learn more about the Draganflyer X8 UAV helicopter on Draganfly’s website. You can also visit the AUVSI website for scheduling, hotel, transport, and entrance fee information regarding the AUVSI 2010 conference.

Similarities between RC Helicopter and RC Airplane Flight

• Both RC helicopters and RC airplanes behave in similar ways when flying forward. Left and right bank will still cause you to turn your heli in the expected direction, and pitching up or down will cause you to slow down or speed up.
• If you can keep track of your RC planes orientation, then it won’t be difficult to do the same with a helicopter.
• The basic radio layout is the same across transmitter modes.

Differences between RC Helicopter and RC Airplane Flight

• Any helicopter pilot who can hover can takeoff and land. With an airplane, taking off and landing is usually considered harder than straight and level flight.
• When flying forward with a helicopter, you have to keep the nose down to keep flying forward.
• Hovering a helicopter is a completely different process than hovering a 3-D airplane.
• Airplanes generally need a larger area to fly in than helicopters.
• When more than one person is flying an airplane at a field, they generally fly planes in a pattern around the runway. Helicopter pilots tend to choose their own zones in the air, which they stay in and do not leave.

Recent radio systems generally have modes for both airplanes and helicopters, but there are a few other differences. RC helicopter radios lack the ratchet that RC airplane radios have on the throttle. The ratchet is great for keeping the throttle setting constant on an RC airplane, but it is not good for helicopters because variations in the throttle setting smaller than the graduations on the ratchet may need to be made. RC helicopter radios also have a 3 position flight mode switch on the left side (normal, idle up 1, idle up 2) and a 2 position throttle hold switch on the right side.

Motors, engines, batteries, and ESCs are usually interchangeable between helicopters and airplanes. Motors that are specifically designed for helicopters use more oil in the fuel and have a larger heatsink.

If you’ve crashed your MASH helicopter and need new rotor blades, grips, or even a new flybar then you’re grounded until new parts arrive. Enter the crash kit – a carefully chosen assortment of the most commonly needed replacement parts, all in one convenient and discounted package. If you keep one of these on hand, you won’t have to stop flying and wait for new parts in the mail again. The MASH helicopter was designed to be user-serviceable just like larger fuel and electric helis. If you’ve got a broken part, then it’s almost certain that it can be replaced without anything more complicated then a screwdriver. This guide will walk you through replacing the most common parts:

Replacing Main Rotor Blades

The main rotor blades can become cracked in a severe crash and pieces can break off. While it’s completely possible to fix small cracks and dings with some medium CA glue and accelerator, this can negatively affect blade balance and make the helicopter vibrate. It’s easier and faster to replace the old blade so here’s how to do it:

1. Get a small Phillips head screwdriver and unscrew the single aluminum screw at the root of the damaged blade. The blade will now be free, and you can remove and dispose of it. Damaged blades can be sharp, so be careful not to cut yourself.
2. All the top rotor blades come with a white warning label on their upper surface. Choose from the upper and lower rotor blades as needed so that the rotors look like this when viewed from the front. As viewed from the front, the right top rotor blade should curve upwards and the bottom right rotor blade should curve downwards. This picture shows the correct blade orientation.
3. Install the replacement blade and tighten the screw just enough so that the blade swings freely when you tilt the helicopter, but is secure enough that it won’t fly off. This has to be done by feel – it’s not critical that the screw is perfectly adjusted, but the blade should feel secure and move freely.
4. Repeat this for any other rotor blades that need replaced. It’s helpful to install them one at a time to keep track of the orientation.

Replacing the Blade Grips

The blade grips / holders are black clevis like objects which clamp down on the root of each blade and hold it to the main shaft. If one of these becomes damaged, use this procedure to replace it:

1. Remove the both of the rotor blades that the blade grips are holding by following the instructions above.
2. Lay the helicopter on its side and observe the two screws that hold the blade grips together and on the main shaft. This picture shows one screw removed, viewed from the bottom of the helicopter.
3. Unscrew the blade grips and keep the screws in a safe place where they can’t roll away.
4. Replace the broken blade grip and install the screws.

Replacing Ball Linkages:

Ball linkages connect the RC helicopter’s servos to the swashplate and flybar. It’s fairly unlikely that these will get broken in a crash, but if they do, here’s how to replace them:

1. Snap off the damaged ball link using your fingers or a screwdriver.
2. Find the replacement link that matches the one you took off and press it on to the spherical plastic nubs where the broken link connected. This picture shows a partially disconnected ball linkage on the flybar:

What makes the MASH helicopter unique is its ability to be completely disassembled and user serviceable. You don’t usually find this on helicopters in the 100 to 200 dollar price range, which are usually meant to be flown and then discarded when they break. Want to learn more about the MASH helicopter, or get one to fly around your living room? RCtoys sells them at a great price. If you just want the crashkit, RCtoys.com has that as well.

The swashplate isn’t included in the crashkit, because it rarely breaks.  If you need a replacement swashplate, you can get one online for a low cost.

The AUVSI (Association for Unmanned Vehicle Systems International) was created in 1972 when the use of unmanned target drones in the Vietnam War prompted the creation of the National Association of Remotely Piloted Vehicles (NARPV). NARPV eventually grew as the industry expanded, leading to the formation of the current AUVSI organization. The AUVSI is promotes the use of Unmanned Aerial Vehicles (UAVs) through education, communication, and leadership. This year’s AUVSI conference is expecting record attendance of over 5000 visitors from over 30 different countries. There will also be more than 100 international speakers giving presentations on the UAV industry and latest developments. This years tradeshow will feature live demonstrations from a wide variety of exhibits. Draganfly Innovations Inc. was the first company to demonstrate live at the AUVSI at the 2009 conference, blazing the trail for other live demonstrations in the following years.

Draganfly Innovations Inc. staff will be flying their RC helicopters indoors, and will be demonstrating their  helicopters features including aerial photography, aerial videography, and the computer controlled base station with wireless telemetry and an HUD display. Because we will be flying indoors we will not be able to demonstrate the GPS hold feature.  The following AUVSI promotional video shows some of the technology that will be present at this years conference.

You can learn more about the Draganflyer UAV helicopters on draganfly.com. You can also visit the AUVSI website for scheduling, hotel, transport, and entrance fee information.

• Apache Longbow, an attack helicopter used by the military
• Blackhawk, one of the most sophisticated manned helicopters in the world
• Coast Guard helicopters which fly over water on rescue missions
• Popular Robinson made helicopters used by the police and civil aviation
• RC Draganflyer X6 and Grumman MQ8 Firescout UAVs

The episode talks about how the Draganflyer RC helicopters use a new and very  very cool flight control system; which controls the RC helicopter by changing each electric motors speed individually. The simplicity and reliability of this design has applications in future helicopter designs, and also makes the Draganflyer X6 UAV perfect for aerial reconnaissance and photography. The Draganflyer X6 UAV helicopter’s advanced flight computer is also demonstrated, and the auto-land and GPS features are shown.

Features of The New Mini Base Station

The Mini Base Station can fit in the pre-cut slots of the soft transport case. Each part is secured with high density foam, which protects and secures parts during transport. The Mini Base Station features a special collapsible design which allows it to deploy in seconds, and fold up for storage. The base station legs are held together with a high tension elastic chord so that they click together easily. The top of the base tripod features a precision machined metal head, which securely locks all 3 collapsible legs together and holds the base station electronics and antennas.

The telemetry software allows you to quickly and easily see what the helicopter is seeing in real time. Geo-tagged photos allow all your aerial pictures to show up in Google Earth and flight data logging shows the GPS position and altitude where each was taken. The Draganflyer UAV’s flight path is also displayed, with photo thumbnails showing where and at what altitude pictures were taken along the flight path. A full compliment of flight instruments is displayed and the display can be quickly toggled between instrument and Heads Up Display mode, which displays critical flight information over a live video feed. The Draganview software is also compatible with all the camera payloads we offer, even special purpose models such as FLIR infrared and low-light night vision.

Unlike the watertight case of the Standard Base Station , the new Mini Base Station uses a lightweight and strong rubber platform to securely hold your laptop or video recording device. The rubber mesh detaches easily for storage in the soft transport case, and sufficiently small laptop computers can even be stored in the case alongside it.

The new Mini Base Station is powered by a high energy density Lithium Polymer Battery for fast charge times and long run times. The included charging station automatically charges and balances the cells in each battery pack, ensuring long life and good performance. The base station electronics are all contained in a precision machined aluminum case.

The Draganflyer X6  RC helicopter was recently featured at the Blue Line Police Tradeshow as part of the Ontario Provincial Police Department’s (OPP) booth. The  Tradeshow runs once each year and provides an opportunity  for companies to demonstrate their products and innovations to Canadian Police Services. These  Include:

• Federal, Provincial, and Municipal Police Agencies
• Parks Canada
• Customs Canada
• The Ministry of the Environment
• Correctional Services

Other security and law enforcement  services that work for hospitals, transit systems, colleges, and also private business attend the Blue Line Tradeshow to keep up with the latest law enforcement technology developments.

This year’s event also had demonstrations of ambidextrous assault rifles, new generation gas masks, and even color-coded handcuffs. As CTV Toronto reports: “It (The Blue Line Tradeshow) comes as the city prepares for the G20 convention and the arrival of some of the world’s top leaders – giving officers a glimpse of how the latest technology can combat everything from rowdy crowds and bomb threats to outward acts of terrorism.”

Security is more than just weapons though, as forensic officer with the Ontario Provincial Police Department (OPP) Richard Cunningham elabortates: “It’s about all the tools that are available to keep the public – and the officers – safe.” Officer Cunningham is one of the Ontario Police Departments two pilots authorized to fly the Draganflyer X6 helicopter UAV. The Ontario police use the Draganflyer X6 UAV helicopter as a stable, secure UAV aerial platform to take pictures and video of crime scenes.

Officer Cunningham goes on to say that the Draganflyer X6 UAV may see other future applications, including those which directly endanger police officers (such as a bomb threat).

You can learn more about the Draganflyer X6 and X4 UAV RC helicopters on our website, or read the CTV Toronto article.

The helicopter became a prominent military asset during the Korean conflict of the early 1950s. The United States Army started using helicopters for medical evacuation in order to increase the survival rate of critically wounded soldiers. Helicopters were used in conjunction with forward mobile army surgical hospitals (MASH units).

When many people think of helicopters being used for medical evacuation in Korea the Bell H13 Sioux (designated the Bell-47 by the US Army) is the one that most comes to mind. Most people know this helicopter as the MASH helicopter because of its important role in the TV series MASH. EF has come out with an amazing flying replica of this famous MASH helicopter.

Included with the EF MASH Rescue Chopper

The EF MASH Rescue Chopper includes everything you need to fly, right out of the box. This is what is included:

• 2.4 GHz 4 Channel Transmitter
• RTF MASH Rescue Chopper
• 7.4v 800 mAh LiPo Battery for the Helicopter
• Two 7.6 gram Micro Servos
• 3 in 1 2.4GHz receiver

Main Features of the EF MASH Rescue Chopper Indoor RTF RC Electric Helicopter

The EF MASH Rescue Chopper is easy and fun to fly while still maintaining the stand off scale looks of the helicopters used in the TV series MASH. The dual rotors (co-axial) make this micro electric helicopter easy to fly and perfect for the beginner RC helicopter pilot. Experienced helicopter pilots can work on there skills to make the flight look as realistic as possible.

It is very quick to get the EF MASH Rescue Chopper ready to fly. All you will need is a screw driver and 8 AA batteries. The MASH Rescue Chopper Indoor RC electric helicopter does require a small amount of assembly. Before you begin the assembly start charging the LiPo battery. This way you will be flying the helicopter in no time.

This mini indoor electric helicopter has a coaxial rotor design which provides great stability, and eliminates the need for a separate tail rotor to control torque induced yaw (rotation around the main rotor axis). Coaxial RC electric helicopters are great for flying indoors, because they are both stable and offer precision control.

A 3.7 volt LiPo battery powers the EF MASH Rescue Chopper for a flight time of eight to ten minutes. The battery is charged in the controlled and takes about 30 minutes to charge. To get maximum enjoyment out of your helicopter it is a good idea to buy a spare battery for it. This way you can be charging a battery while flying and cut down your down time.

If you do happen to have a mishap and crash the MASH Rescue Chopper you will be amazed at how incredibly resilient it is. However things do and can break, but not to worry as a full line of inexpensive replacement parts are also offered for this helicopter.

In summary if you want to try some basic scale electric RC Helicopter flying you should look into buying the EF MASH Rescue Helicopter.

When this base station is combined with a lap top the Draganfly Wireless Video & Telemetry Base Station you can view video and telemetry from the helicopter in real time. Dragan View software ships with the base station and provides a lot of added features.

When you are using one of the Draganflyer Helicopters to take pictures, the GPS information is recorded. You can then use the Dragan View software to show you a 3D representation of your flight path on Google Earth™, showing you where you took the individual pictures. With in Google Earth™ you can click on the thumbnail of the picture to bring up a full size version. Along the top of the full size version the longitude, latitude, and altitude information is displayed.

The wireless video & telemetry base station also provides you with an analog video out. This means you can connect it to an external monitor so others can see what the helicopter sees in real time. With the video also being sent to the lap top you can use an application like Snap Security to stream your video to your iPhone. Draganfly Innovations wireless video & telemetry base station is truly a neat piece of gear to have.

Included with the EVO Flight Mini Stinger

The EVO Flight Mini Stinger includes everything you need to fly, right out of the box. Here’s what is included:

• The EVO Flight Mini Stinger Micro RC Helicopter
• A 2.4 GHz, DSM-2 Spread Spectrum Transmitter (requires 4AA Batteries)
• A Portable Lipo Charger built into the transmitter
• 1 cell 3.7V 110mAh Li-Po Battery

The Evo Flight Mini Stinger is great for beginner and experienced pilots, because you do not have to buy any additional parts. You can use this helicopter to get experience and practice your orientation indoors when you cannot fly outdoors because of the weather.

Main Features of the Evo Flight Mini Stinger Indoor RTF RC Electric Helicopter

Like the Blade MCX the Evo Flight Mini Stinger has a proportional four channel radio. Four channel control means that pilots can fly the helicopter with four dimensions of freedom. The Evo Flight Mini Stinger can fly up/down, rotate left/right, pitch forwards/backwards, and bank left/right. With a four channel radio you can precisely control the Evo Flight Mini Stingers’ movement through all three dimensions. With a rotor size of 188mm (7.4”) and a length of 213mm (8.4”) this helicopter can easily fit in the palm of your hand.

The coaxial rotor design of the EVO Flight Mini Stinger provides this helicopter with great stability, and eliminates the need for a separate tail rotor to control yaw (rotation about the main rotor axis). The main rotors spin in opposite directions, canceling out rotor torque caused by their rotation. Coaxial RC helicopter are great for flying indoors, because of their stability and the precision control provided.

The Evo Flight Mini Stinger uses a tiny 1 cell lithium polymer battery for power. Unlike most micro RC helicopters, the battery is removable and interchangeable. Each cell provides 3.7 volts of power with a capacity of 110 mAh (Milli ampere hours). You charge the battery using the included transmitter, which runs off four “AA” alkaline batteries. A typical charge takes about 30 minutes and provides an average flight time of 6 to 8 minutes. Because the battery is interchangeable, we recommend that you purchase an extra so that you can use one while the other is charging.

Weighing only 1 ounce, the Evo Flight Mini Stinger is virtually crash proof. A sudden drop from a few feet above the ground won’t damage it, and in most cases minor collisions with walls are not a problem. Although it is not indestructible, the Evo Flights durability makes it an ideal present for anyone over 12 years of age.
If you want to get into the exciting world of RC helicopters, the Evo Flight Mini Stinger makes a great starting place. It will show you all the basics of RC helicopter flight, and can be used as a starting place to more advanced models. If you’re already an experienced RC helicopter pilot, you’ll like the Mini Stingers control and stability.

UAV Option New to Law Enforcement Across the Country

By Heather S. Benjamin, PIO/Information and Communication Manager
Mesa County Sheriff’s Office, Colorado

On August 31, 2009, the Mesa County Sheriff’s Office, Colorado attained monumental authorization from the U.S. Department of Transportation – Federal Aviation Administration (FAA) for Unmanned Aerial Systems (UAS) operations. The authorization granted by the FAA allows the Sheriff’s Office to conduct tests and evaluation flights of an unmanned aerial vehicle (UAV), the Draganflyer X6, by receiving a Certificate of Waiver or Authorization (COA). The COA is granted by the FAA for a one year period allowing the agency to test their UAV.

The Draganflyer X6 was chosen mainly because it fit the COA requirements and fit the needs of our agency simultaneously, with our desire to make the FAA process as stream lined as possible. Ben Miller says he reviewed at least 50 various UAV products before selecting the Draganflyer X6.

This comes after an 18 month research project where extensive thought and comparison of UAVs, cost, application process with the FAA, and more were considered. Most recently, the Sheriff’s Office completed a six month application process through the FAA to receive a COA and has since begun to evaluate the UAV. COAs are known amongst the UAS industry as moderately unattainable and even agencies like the National Aeronautics and Space Administration have been denied, according to the FAA website.

The Draganflyer X6 is a small, remotely operated, electric helicopter built by Draganfly Innovations of Saskatchewan, Canada. Built of mostly carbon fiber the Draganflyer X6 overall weight is just over two pounds and can carry a payload of just over one pound. Payloads include the FLIR Tau infrared camera and a Panasonic Lumix LX3 digital still camera. Payloads are remotely operated and real time images/video are visible via a laptop operated on a ground station.

Operations of unmanned aerial vehicles by public agencies in the National Airspace (NAS) is a predominantly uncharted territory and thus the FAA regulations are considered interim at best, according to the FAA website. The Sheriff’s Office hopes to provide flight mission data to the FAA to aid them in the drafting of federal aviation regulations to govern the use of these small unmanned systems. The COA provides the Sheriff’s Office approval to fly the Draganflyer X6 in an area two miles in diameter located five miles southeast of the Grand Junction Regional Airport with an operational ceiling no greater than 400 feet above ground level (AGL). These flights must remain visual line of sight (VLOS) and are not allowed after dark. Local air traffic must be contacted 24 hours and 15 minutes prior to flight as well as filing a Notice to Airmen (NOTAM) describing specific flight operations.

“This is an applicable technology to law enforcement that I am convinced will save lives,” the Sheriff’s Office Quartermaster Ben Miller, said. Miller is one of two employees who are trained to operate the Draganflyer X6.

The Draganflyer X6 model is priced at about $25,000 US dollars in 2009, but the Sheriff’s Office currently has it under a lease agreement. The company, Draganfly Innovations Incorporated is a privately owned company who have been a pleasure to work with through this process, Miller said. Draganfly has a relationship with law enforcement in Canada, most likely based on the location of the company and thus was excited to work with a U.S. law enforcement agency who is enthusiastic about venturing in new FAA territory.

Without trying any products but deciding on the Draganflyer X6, as an agency we couldn’t justify an outright purchase of the product. The FAA won’t permit demonstrations of UAVs without COAs. Thus, we were limited to on-line videos and personal recommendations, and technical articles to help us make our decision on the product that most fit our project guidelines.

“Right now we don’t own this equipment. We’re struggling to figure out how this exceptional technology that we believe will save lives can fit in an environment where out budget is cut and our employees are losing ground in employment benefits as cost savings measures are continually implemented by our County government,” Sheriff Stan Hilkey said. “Using tax payer funds for this type of important research and development has never been more unpopular. When and if the time comes to try and purchase this equipment we may attempt to use seized drug funds from our local seizure board, which will make this more acceptable to our struggling constituency, and also increase the collaboration with the resource as the seizure board has broad representation from all law enforcement agencies in our County.”

The Draganflyer X6 was chosen mainly because it fit the COA requirements and fit the needs of our agency simultaneously, with our desire to make the FAA process as stream lined as possible. Ben Miller says he reviewed at least 50 various UAV products before selecting the Draganflyer X6.

The Mesa County Sheriff’s Office has, to date, conducted over 72 Search and Rescue (SAR) missions in 2009. “With the ability to attain a bird’s eye view of a search area for a fraction of the cost of operating full-scale aviation assets, UAS technology is a great fit,” Hilkey said.

In direct reference to a SAR mission, anytime you have terrain that takes time to get across, you will save significant time by flying it. The perspective of having eyes at ground level – essentially

six feet off the ground, versus having ‘eyes’ 200 feet off the ground – is greatly beneficial when looking at a vast amount of terrain. We can over lap that view with maps, information from the reporting party and this is one way to make a quicker incident action plan, and in Colorado less time to rescue equals more lives saved. We do anticipate that an initial

deployment during the first phases of a ‘hasty searching’ that occurs in SAR events could potentially save man hours and volunteer hours in the field.

Our effort is solidly based on the desire to add tools to make our jobs easier and safer, Hilkey emphasizes. In the SAR aspect, if we can deploy and find either our objective or clues to it, then it has proven to be valuable, especially in circumstances where persons are at risk due to climate, terrain, health, etc. In a tactical aspect, the measurement would be more in officer safety. How can we measure the ability to see hostile threats, or tactically be safer because we know the layout of a compound, terrain, etc., Hilkey went on to say.

Over the summer months of 2009, about 40 miles outside of Grand Junction, in a remote area along a two lane state highway, a pick-up truck with a trailer attached and a semi-truck crashed spilling hundreds of gallons of an acidic material. The Grand Junction Haz-Mat team arrived, but not before a number of first responders who attempted to control traffic and assist the occupants of the vehicles were exposed to toxic gases. Hazardous fumes were a major concern and trying to determine a safe boundary for all involved as well as the media took several hours. It is anticipated that the Draganflyer X6 could have been put in the air, above the spill with either live video and/or sensor payloads to quickly determine a safe range from the acidic fumes and total size of contaminated area.

The X6 can also provide crime scene photographs, evidentiary search support and real time mission data to special response teams inside law enforcement. Tactical operations, such as a previous incident where we had a man who was thought to have barricaded himself in his house or position himself in the field surrounding his house. But deputies knew he had weapons and he was believed to be a danger to law enforcement. Looking back on that SWAT operation that took several hours through the night and into the early morning, Commanders on-scene believe that if we had the Draganflyer X6 in operation at the time, it could have been used to clear the farm field surrounding the suspect’s house. The man hours, the labor and the time it took to surround a large farm field – covering about ¼ of a mile around the house – could have been cut down to 20 or 30 minutes with one man operating the Draganflyer X6.

These are only a few examples of how Hilkey and his staff hope to put the Draganflyer X6 to use over the next year, really putting it to the test of this agency’s needs and thoroughly testing it for all the benefits to law enforcement. For any agency interested in learning more about the testing phase or the equipment being used by the Mesa County Sheriff’s Office, email Miller at Benjamin.Miller@mesacounty.us.

The weather was extremely cold with winds blowing at 20kmh/12.4mph creating a wind chill of -37°C / -34.6°F . The Draganflyer X6 and held hand transmitter unit performed extremely well in these harsh conditions. The only limitations that were encounter were that of the operators’ hands becoming too cold to fly. In order to remedy this, the operators switched off. While one operator was flying the Draganflyer X6 the other operated sat in a warm vehicle to warm their hands.

The Draganflyer X6 UAV RC Helicopter was used to take aerial photos of the scene of this urban traffic accident. The aerial of photos of this accident will be used by the Saskatoon Police to provide clear evidence for use in their investigation of this traffic accident.

Draganfly Innovations operating under approval of Transport Canada is able to provide assistance to police agencies with Draganflyer UAV helicopters day or night with in a 250 km radius of the city of Saskatoon in rural or urban environments. This 250 km range covers 10 of the 15 cities in Saskatchewan.

The Ontario Provincial Police (Kenora and Thunder Bay) operating under transport Canada approval is able to operate Draganflyer UAV helicopters in the province of Ontario. The Draganflyer X6 represents the first federally approved, commercially produced Unmanned Aerial Vehicle by an emergency service in North America.

To build one of these panoramic virtual tours aDraganflyer X6 or Draganflyer X4 is flown to the desired altitude. At which point aerial photos are taken at every 20° for a total of 18 aerial photos. Then a photo is taken with the camera facing directly down. Then the photos will be combined by using panorama tools graphical interface (PTgui) software.

For more information on how to get your Draganlfyer X6 or Draganflyer X4 pictures made into a virtual panoramic tour we recommend you check out the PTgui forums or contact NorthStudio.com.

Using the Draganflyer X6 UAV RC Helicopter to take aerial pictures of the scene provides the police with clear evidence to use in their investigation. Because the Draganflyer X6 can be rapidly deployed the police are able to minimize the amount of time the road way had to be closed from traffic. It is far quicker and easier for the police to use the Draganflyer X6 than to use a conventional aircraft or boom truck.

This is not the first time the Draganflyer X6 UAV RC Helicopter has been used by the Saskatoon Police Service. On May 28 2009 the Draganflyer X6 saw its first operation use in traffic collision photography.

Both the Ontario Provincial Police and the Saskatoon Police Service have been approved by Transport Canada to use the Draganflyer X6 in their daily operations. Recently the Draganflyer X6 and the Ontario Provincial Police were featured in Blueline magazine. Blueline magazine is the premiere Canadian Law Enforcement magazine.

The Draganflyer X6 has also received approval by the United States Federal Aviation Authority in the form of a certificate of authority (COA) to be operated by the Mesa County Sheriff for use in their policing operations.

UAV RC Helicopters are becoming extremely useful tools for police agencies. They have the benefits of reducing the cost of obtaining aerial photographs in evidence gathering as well as being very quick to deploy. By being able to be deployed quickly they help the police gather evidence faster and in the case of traffic accidents allow the police to get traffic moving again sooner.

This video depicts the Draganflyer X4 RC Helicopter being quickly set up and flown from its case which has an optional detectable back pack harness.

In this video we see the Draganflyer X4 being transported in its soft pack with back pack harness on a man riding a mountain bike. This truly shows has easy it is to pack the Draganflyer X4 into a remote location.

One of the camera payloads the Draganflyer X4 RC Helicopter can carry is the Panasonic FX-580 12.1 Mega Pixel Digital Still camera. This video gives a good description of how this camera integrates with in the Draganflyer X4 System.

This video gives us a picture in picture of what the camera sees as the rc helicopter is flying. The video is transmitted live while recording to the on board digital video camera.

Another camera payload option for the Draganflyer X4 is a micro video board camera with a on board digital video recorder. This video gives you the details of the Micro Video board camera.

The Draganflyer X4 RC Helicopter, as demonstrated by these videos, is a very versitile and portable UAV aerial video and aerial photography platform. We here at RCHelicopter.com will be looking for new videos from Draganfly Innovations.

Flying unmanned aerial vehicles in the United States is governed by the FAA as they control the airspace. In order to operate a UAV in US airspace you must receive authorization from the the FAA. The FAA currently classifies all UAVs’ including the Draganflyer X6 as a reconnaissance unmanned aerial vehicle. This is the same classification used for the aerial vehicles that the military uses in places like Iraq and Afghanistan.

The Mesa County Sheriffs office had to complete a complicated permitting process, meeting all the stiff FAA requirements specifically in the area of safety. The Draganflyer X6 was able to met all the requirements imposed by the Federal Aviation Administration. This allows the Mesa County Sheriffs Office to obtain a certificate of authority (COA) from the FAA. By obtaining the certificate of authority the Mesa county Sheriffs office can submit a Notice to Airmen to the FAA which in turn allows them to conduct operations with the Draganflyer X6.
