roto bak plate for hpi rs4 super nitro
Ihave a hpi super nitro rs4 with a picco xp .15 engine and i am looking to replace the pull start. It looks to me like it is a smaller hex head that the backplate need to fit. I ordered one online but it fit a picco engine with a bigger hex head. anyone know what part number that would be?
