When the RC helicopters starts to act strange you should take the RC
helicopter down and inspect every part of the RC helicopter.
Look over the way the parts were installed and see if you did the proper
Try to work 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.
This might seem like an inconvenience but it’s better than crashing and
paying money for a crash that could have been avoided.
When the radio and receiver are turned on, that’s when you are supposed
to notice anything different with your helicopter. Hear for noises that
come from the servos.
Are they working properly?
If the servo inspection goes well, while securely holding the main rotor,
turn on the engine and hear how the engine sounds.
Does the engine sound normal?
As you fly more and more you will know how the engine is supposed to
sound to you.
Just remember that if at any time the RC helicopter acts funny put that
helicopter down and run the trouble shooting technique.
Please don’t ignore this tip.
Trust me, you will develop your own technique but for now just follow
what’s on this site. Use this site as a good trouble shooting source or
go to the forums to find what you can’t find here. But please make sure
you find the problem or you will be spending money on parts due to a crash.
One last thing that I want to mention is that if you have a problem with
the RC helicopter while in flight, try not to panic just bring the RC
helicopter down slowly. Bringing the RC helicopter fast will just make
controlling the helicopter harder.
Try to stay calm while slowly lowering the RC helicopter down to the
ground. Once it’s on the ground be sure to inspect it thoroughly.
