After the work and time you have invested in your RC helicopter, it can be disturbing to realize that something is not working correctly, especially if your machine is still in the air. And worse come to worst, you RC helicopter will probably crash, and eventually learn for your faults. The most common mistakes that resulted to an awful crashing of RC helicopters are the following:
Not checking right away any slight changes in the RC helicopter’s flight performance. The slight changes of the heli’s flight signifies malfunctioning and defects on its parts. Work with the details, from the tail rotor all the way to the canopy. There could be potential problems that you will not know about until it is too late.
Fail to remember that an engine problem may occur periodically, if you missed checking the engine, the probability of crashing your RC helicopter is high.
Not checking the proper movement of all the servos – including the throttle servo. If the servo was also reversed and not properly positioned, that can cause the engine to start at full throttle even though the throttle stick was at idle. This could result of losing control to the RC helicopter.
Failure to use simulator for the beginners, the hardest part of flying a helicopter is developing the “reflexes” and the “delicate touch” necessary to instinctively correct the tilt/direction of a helicopter. A simulator will help you develop these skills quickly without spending a lot of money on replacement parts.
Failure to pin the tail rotor to the boom, and also failing to pin the boom to the side frame can result into a drastic damage and eventually crash the RC helicopter. The tail rotor shaft bearings may also incur damage if the tail blades touch the ground and it should also be checked periodically and cleaned or replaced if necessary. To do this, drill a small hole through the tail rotor gearbox into the tail boom.
The bolt will make its own threads, and should be just long enough to go through both the tail rotor gearbox and the tail boom without hitting the driveshaft or belt. Another pin at the other end of the tail boom will secure it to the side frame. This will keep the tail rotor and boom secure in flight no matter how hard you maneuver, yet are still easily removed for maintenance. Follow these tips to avoid a helicopter crash.
