Abstract: A helicopter tug system features a helicopter with skids. A powered track assembly features a microprocessor connected to a power supply, a drive hub and an idler hub, a track located on the drive hub and the idler hub, a motor connected to the drive hub and the power supply, a receiver connected to the microprocessor, and a clamp located on a track assembly top. A caster support features a caster support frame having a wheel and the clamp located on a caster support frame top. The system features a radio control unit with a transmitter and a radio control power supply. A first powered track assembly is attached to the first helicopter skid and a first caster support is attached to the second helicopter skid. The radio control unit sends a first signal to the first track assembly to move the helicopter.

Abstract: An improved aircraft towing vehicle includes a base plate, a controller and two drive motors supported by two track assemblies. A pivoting wheel constraint mechanism rests on the base plate and includes a front roller mount, a rear roller mount and a linkage connecting the front roller mount and the rear roller mount. When the rear roller mount is pushed or otherwise urged backward, the linkage causes the front roller mount to pivot upward to confine an aircraft wheel on the base plate. A latch keep is also connected to the base plate for holding the rear roller mount in the backward position and locking the wheel constraining mechanism for moving an aircraft.
