Available from HPI Racing is our Roto Start system for HPI .12, .15 and .18 engines!

The HPI Roto Start system replaces the standard pullstarter with a durable metal gear backplate and a handheld shaft driven starter. Starting is as simple as pressing a button. Requires a 7.2v rechargeable "stick" battery pack and charger. Complete instructions included.

Note: Some disassembly of the engine is required to convert engine from pull-start.
