It can be used indoors and can be manufactured around ultra–low cost rolled paper tubes capped at one end. The variables affecting performance include wheel types, bearings, body design, overall weight and even suspension. The launcher air pressure can be varied (and monitored using the built in pressure gauge) so that a typical car will travel slowly just a few metres or at very high speed several tens of metres. The starter pack includes: Launcher, firing box (requires 2 x PP3 batteries), car body mandrel, sample nose caps, corriflute base, wheels and axles. Foot pump required and sold separately.
