Abstract:
In a scale model vehicle including a chassis, a main drive shaft mounted for clockwise and counterclockwise rotation on the chassis, drive wheels coupled to the main drive shaft for propelling the vehicle in forward and reverse directions, an internal combustion engine having a rotary power output shaft, and a transmission assembly coupled to the rotary power output shaft for transmitting torque from the engine to the main drive shaft, the transmission assembly comprising:a first clutch coupled to the main drive shaft for transmitting torque in a clockwise direction; a second clutch coupled to the main drive shaft for transmitting torque in a counterclockwise direction; a clutch bell coupled in torque transmitting engagement with the main drive shaft, the clutch bell being movable to a forward drive position in which the clutch bell is engagable with the first clutch for transmitting torque to the main drive shaft in the clockwise direction, and movable to a reverse drive position in which the clutch bell is engagable with the second clutch for transmitting torque to the main drive shaft in the counterclockwise direction; and inertial lock-out apparatus movably coupled to at least one of the first and second clutches for radial extension into a blocking position which prevents movement of the clutch bell from one drive position to the other drive position when the engine is operating above a predetermined idle speed.
