There is provided a method and apparatus for controlling a toy helicopter in flight. The toy helicopter is powered by a first rotor and a second rotor. A target speed ratio is determined for the speed of the first rotor and the speed of the second rotor. The speed of the rotors is adjusted incrementally until the target ratio is achieved.
1. A method for controlling a helicopter, the helicopter having a first rotor and a second rotor, the method comprising the steps of: (a) measuring a speed of the first rotor;(b) determining a target second rotor speed based on the speed of the first rotor;(c) measuring a speed of the second rotor;(d) if the speed of the second rotor is greater than the target second rotor speed, decreasing power to the second rotor by a fixed increment;(e) if the speed of the second rotor is less than the target second rotor speed, increasing power to the second rotor b...
