ABSTRACT:
A portable test stand and track simulator for radio-controlled model racers has a cylindrical drum journalled for free rotation between arms extending from a vertical post pivotally mounted within aligned openings of a bracket attached to the upright slanted handle portion of a wheelable support frame. The drum is larger than the racer and has a circumferential surface that is covered with a polyethylene pile or other terrain simulating material. An open box-like basket fixed to the frame handle serves to hold the front or back wheels of the vehicle with the aid of pins passing through basket perforations, while the other wheels are positioned on the drum surface. A generator or cyclocomputer is arranged to determine the speed at which the drum surface is driven by the restrained car. Markers on a drum support wheel provide stroboscopic calibration. A crank handle balanced by an oppositely positioned counterweight serves to rotate the drum manually. A stop pin passing horizontally through the vertical pivot post extends through a slot in the bracket to limit lateral drum articulation, and a latch rotatably attached to the bracket selectively captures the pin to wholly prevent the articulation when desired.
