Follow these maintenance tips to keep your RC helicopter looking and flying like new.

• Canopy - The canopy off your rc helicopter and check it for cracks and other defects. If your canopy was glued together from two halves, make sure that it’s not splitting at the seam. If the canopy mounting holes are enlarged from vibration then they won’t hold screws well. Fix this by placing large washers between the screws and the canopy.
• Servo Tray - Make sure that the servo tray isn’t cracked, and that it’s fastened securely to the fuselage.
• Frame - Ensure that all bolts and screws are tight. If you find any that have vibrated loose, tighten them with a screwdriver and secure them using a thread locking compound.
• Bearings - Bearings are moving parts, so they wear out over time. Make sure that they move freely and lubricate / replace them as needed.
• Landing Gear - Check the landing gear for any signs of stress or damage. If bolts are loose, be sure to tighten them and hold them in place with thread lock.
• Tail Boom - Depending on the type of RC helicopter you have, check the belt or the shaft for signs of wear. If you’re storing the RC helicopter for a long period of time release the belt drive tension.
• Fuel Tank - Be sure to drain all the fuel in the tank, then dissasemble it and make sure that the fuel lines are secure and that the clunk can swing freely.
• Gear Box - Disassemble the tail rotor gear box and lubricate each part. tighten any loose screws.
• Batteries - There are many different opinions about storing and caring for rechargeable batteries. In general: don’t over discharge your cells, store at a 50 percent charge, and cycle regularly to gauge performance. Batteries should be replaced after their performance begins to decrease. If you want to store your batteries over the winter, keep them inside where it’s warm. No battery reacts well to freezing.
• Rubber Grommets - The rubber grommets that servos are mounted to can dry out over time. Prevent this by lightly coating them with petroleum jelly.
• Servo Arms - Check all the servo arms and make sure that none are cracked.
• Clevises - Make sure that the clevises are securely fastened to the servo horns. You can secure the clevises by slipping a small piece of fuel tubing over the closed clevises.

We hope that these tips help you keep your RC helicopters performing well.
