I bought the Comanche, because I had a coax previously. The helicopter is difficult to control when the battery's full performance with the trim I have to make myself more familiar! To keep trimming the helicopter and simultaneously in the floating position is not easy! To which I have found that the longitudinal axis of the rotor to the fuselage at a slight angle is I do not like that!
My conclusion: The best somewhere looking for a place where you can fly undisturbed, and the helicopter trims and can become familiar with the controller!
