ABSTRACT:
A remote control toy helicopter has a main rotor and an auxiliary rotor both driven by a rotor shaft. The auxiliary rotor has elongated elements at an acute angle relative to blades of the main rotor. A control system is provided that includes an actuator for engaging with a control assembly depending from the auxiliary rotor. The inter-engagement of the actuator and the control assembly effects change in the angle of incidence of the elongated elements of the auxiliary rotor. The interaction occurs when the assembly engages with the actuator by a depending arm associated with the assembly.
