LOL, Good one!

On a more serious note now, the tail also is mainly for looks, these don't go fast enough to need a rudder.

Status: offline 		I think you would need 2 then because you would have to control both motors. Personally I don't think these helis are worth the expense of some thing like HH gyros.

Guess again Raz, then go to the FAA website and look up some ref docs on flight dynamics.
