The Tamiya 15183 Mini 4WD Speed Checker is designed to let racers and hobbyists capture run times for 1:32 Mini 4WD cars. By timing a car over a fixed distance, it provides the numbers needed to compute average speed and evaluate component changes. The device serves as a practical timer and speed reference for setup work.
Made for 1:32 Mini 4WD chassis, the Tamiya Speed Checker times runs across distances suitable for short tests up to extended timed runs. This lets you compare motors, gear ratios, and wheel types under consistent conditions for more informed tuning decisions.
Use the unit indoors or on a flat outdoor surface to check modifications before heading to the track. Regular timed tests help isolate performance gains and make it easier to dial in motor and gearing choices.
