I remember a bloke a work buying a radio controlled helicopter.
He said you start by tieing the helicopter to a stake with about 1ft of string to stop you crashing it too badly - something to do with them having 8 planes of movement:
left/right cyclic = roll
fore/aft cyclic = airspeed
left/right yaw = yaw
collective pitch/throttle = climb / dive
I suppose once you can co-ordinate all that lot you're sorted!!!
I'll stick to my mini-science up/down simple hovercraft ...
Cheers,
