The Stealth series of Controllers are the only Controllers made in Australia using parts from Australia, Japan and the USA.

The purpose of the Stealth is to eliminate throttle lag and give your vehicle much crisper acceleration. We have seen 1/8m times improve by 0.32 seconds (please note, this is not 1/4m, it was on the 1/8m which makes it more impressive). We have further information using HPTUNERS and extra data here.
