I have just bought a Twin Rotor Beginners Heli, got it, New, for 50quid. Now when I wreck it, which I will, I can strip it down and I will have, 2 Ball raced 400 size motors, a Lipo , 7.4 volt pack with Charger, Tx and Rx on 40Mhz. with a proportional Speed controller. As this Heli steers by slowing one Rotor while speeding up the other, seems that would fit well into a twin prop boat, or am I wrong?Oh and it has a Gyro as well, now where will that go in a boat???!!
