Abstract
Gyro stabilized remote controlled toy motorcycle having good stability and controllability without using ground contacting auxiliary wheels or the like. The motorcycle comprises a chassis supporting a fixed angle rear wheel drive and associated motor and a castered front wheel. A gyro wheel having an axis nominally parallel to the axis of the rear wheel is mounted in a gimbal with a vertical axis in the forward part of the chassis and connected to the front wheel fork and post to turn the front wheel responsive to the rotation of the gimbal relative to the chassis. The chassis further includes a radio receiver, battery power and a steering device, such as a motor and slip clutch for torquing the gyro wheel gimbal. To turn in a first direction the gyro gimbal is torqued in the opposite direction, initially causing the front wheel to also turn in the opposite direction. As the motorcycle and the gyro lean into the turn, a correcting torque is generated by the gyro and caster of the front wheel, overcoming the initial steering torque to maintain the proper steering angle and balance for the motorcycle. Various embodiments are disclosed.
