| 説明 | This electric ir controlled helicopter has a rather unusual control system. For pitch motion the upper and lower rotors are driven by separate motors. By altering the power the chopper torques left or right. The upward facing tail rotor provides forward / backward flight purely by tilting the fuselage and rotor disks. Clever these Chinese! |
