Does anyone know of a quality coaxial helicopter, I have been looking but have had a hard time finding one. I'm looking for something that flies on a 11.1 volt setup and is about the same body size a 450 Trex. Nitro models has something in about this size and the body looks like decent quality but the rotor mechanism looks a little cheesy. I wonder why nobody has developed one, they are naturally more stable then single rotor helicopters and there is no reason they can't be high performance.
