After all the time and effort you put into your machine, it can be troubling to notice that something is not working correctly, especially when the helicopter is still in the air. The most important thing to do at that point is bring the heli back to the ground safely, so you can inspect its parts. Dont panic, as this could affect your control and ability to bring the helicopter to the ground slowly and safely.

With your RC helicopter safely on the ground, start up the engine and listen for strange rattles or sputtering noises. Tail jerking when flying can be a sign that the drive shaft or belts may be loose or skipping. Sputtering noises are often indicative of low fuel levels, or air in the fuel intake. Vibrations are often caused by bent, mismatched or imbalanced parts. Bring a set of small screwdrivers with you when you go flying so you will have the tools for quick tune-ups as needed.

Begin by inspecting the helicopter from tail rotor to canopy, ensuring thatallparts are securely and properly attached. Check all belts, the gyro mount and balancing of blades and fans. If you are using training gear, thiscan turnamildvibrationinto a violent shake, but it can be easily fixed byrunning a different head speed oradjusting thelength of the training gear and howit is fastened to thestruts. Also grease any bearings that require grease, especially in the tail gear.

Next,look for any loose connections inside the receiver. Then,turn on the radio and receiver. Check its battery life first, and then listen for any odd noises that could be from interfering radio or television stations. Sometimes, if you are flying in an area close to other RCs or electronic equipment, those can also interfere with the signal. Make sure that the antenna or any other metal pieces are not touching any metal. When using the heli, the best signal will come from pointing the antenna at a 45 degree angle instead of directly at the copter.

Most importantly, resist the urge to fly the helicopter after youve noticed a problem. Although the repair efforts will cost you time that could be spent enjoying your machine, it's nothing compared to the costs associated with a crash or total replacement of the heli. If you are unable to find the problem, visit a local hobby store. They may be able to help you pinpoint the source of the malfunction.
