The distance between the centre of the fixed mounting holes is 27mm top right to bottom right - this is the same size as standard pull starts for HSP models and therefore the roto start back plate simply bolts straight on with the provided screws.
Fits all 1/10th HSP models sold by Serious-RC. Please note you will need a HSP drill-starter to use this. Do not use high-torque DIY style power drills as it will cause engine damage.
