Never even got the thing to full speed, the pilot was so nervous about flying it he stalled and spun it after half an orbit. The only thing that didn't shatter was the tail.I have been flying RC planes for around 3 years now with only one major wreck . The wreck kind of sucked . I hit a parked school bus

Hance wrote:The coaxials are all smaller in size so you cant fly them outside unless its dead calm the wind just blows them away. The way they are built you cant do any 3D stuff with them at all. Basically the body of the heli hangs off the blades and the blades stay level all the time. They will fly forward, backward, right, left, up, down and you have rudder control but they cant do any cool stuff with them.

That's odd, as everything I've read about real-world coaxials says they're more maneuverable in 3D than single-rotor/tail rotor designs. I wonder if stepping up to gas power would "fix" that problem (while eliminating indoor activities)?
Hance wrote:The top set of rotors is free floating ( no contol inputs go to them). The flybar has brass weights in it. With the top rotor being free floating and the addition of brass weights to the flybar to help counteract what the botom rotor does you gain stability but loose all 3D ability in the process.
