ABSTRACT:
A remote controlled model landsailer includes a wheeled vehicle having a sail supported on a mast with a fixed rig position, in which realistic heeling is produced by an outrigger structure including a transversely-mounted resilient wire having wheels at either end thereof, with the elasticity of the wire providing for realistic heeling of the vehicle while at the same time preventing the vehicle capsizing. The model landsailer is remote controlled, in one embodiment, with a single remote control radio channel which is utilized to control the position of the nose wheel of a three-wheel support structure, with the single channel radio controlled operation permitting all sailing maneuvers including heading up, jibes, tacking, coming about and runs, and with the flexible wire outrigger providing realistic visual feedback to the operator of the radio control unit. Features of the vehicle include single pivot steering, a mast which serves as an antenna, a fixed position lateen rig, a one piece slip pocket sail, and a boom and yard coupling which permits rotation about the longitudinal axis of these elements to permit sail shaping.
