What happens if the motor fails on your RC helicopter mid-flight? Why doesn’t the copter come crashing down in a blaze of glory? It’s all to do with autorotation.
There are many difficult skills you will have to learn when you start a new hobby with RC helicopters, but none are more important than how to control your copter if you run into problems when using it. Autorotation is really difficult to learn, especially if you are a novice, but it is essential that you know what it is because at some point in your RC helicopter flying career you are likely to need it.
Basically autorotation is when your copters blades spin without the motor engaged. The continuing momentum of the blades joined with the motion of the air passing over the blades keeps copter in the air – just. This will mean your copter descends slowly before landing. During this phase the copter is really difficult to control, so it is worth practicing this skill before you are actually faced with a real emergency situation.
