Fits HPI Savage X, 21, & 25 trucks, as well as Ofna Force 21 & 25 engines

This is an HPI Roto-Start System for the HPI Savage X, 21, and Savage 25 trucks, as well as the HPI G3.0 engine.  This will also work on the Ofna Force 21 and 25 engines.  If you want something to fire that glow engine up easier than pull-starting, this is what you need.  Included are the Roto-Start, the starter shaft, and the engine backplate, with tough metal gears.  These are a must for a serious Savage owner.
