HPI Roto Start 2 System (For Nitro Star F Series Pullstart)
Start your vehicle quickly and easily with the updated Roto Start 2. The Roto Start 2 features a more durable case and to protect your engine it comes with a built in circuit breaker which cuts off in case of an overload (e.g. a flooded engine).
This HPI Nitro Roto Start 2 system is for the F & G series engines that use a 12mm One-Way Bearing.
The F3.5 V2, F4.6 V2, and G3.0 HO engines use a 14mm One-Way Bearing. For these engines use backplate #113736 or change the bearing to #1430.
Note: When using this system for the Trophy Truggy, whilst not essential, using starter shaft #87104 will give you some extra reach to the back of the engine.
