Abstract
A tricycle-type wind-propelled toy land vehicle includes a sail with reliable tangle-free boom control. Both the disposition of the boom and the front wheel steering is actuated by a radio frequency remote control system. The vehicle further includes a skid plate surrounding the front wheel to prevent tip-over. The front wheel is steered by a worm gear drive which is self-locking. Boom control is provided by a guided cable system or, in an alternate embodiment, a direct gear drive to rotate the mast. In yet another embodiment, boom control is provided by a sliding leaf spring which passes underneath the boom and attaches to a track on the underside of the boom.
