HPI Roto Start 2 System (K Series with Long Shaft For Savage XL etc.)
This is a complete HPI Nitro Roto Start 2 system for the K series of Nitro Star engines. It has an extra long shaft for fitting trucks like the Savage XL.
Works well and prevents hurting your hands on a pull start. The shaft also clips on the bottom of the device for easy storage. Only a pity that HPI couldn't standardise on the size of the hex for the shaft so I can also use my hyper torque start shaft on it. For reference the hex size is 5.5mm.
