Roto Start 2 System by HPI Racing
This is the HPI Roto Start 2 System. This version includes a back plate that works with HPI's K series Nitro Star engines, as well as all necessary hardware. The Roto Start 2 features a more durable case and comes with a built in circuit breaker which cuts off in case of an overload (e.g. a flooded engine) to protect your engine. This system also includes an extra long shaft for fitting trucks like the Savage XL. A 7.2V stick battery pack is required and not included.
This product is expected to arrive on Friday, December 23 2016.
