Thanks Mark by looking at Dans pics it looks prity small and could se how it would fail on a rally stage when it gets bashed into gear after a spin/crash but for it to just go in general slow movement use ??? From what i felt today there was nuthing in reverse where i would think if the dogs were sheared there would be vibration on the bits left when keeping pressure on the stick.

This is Dans stripped pics(hope he doesnt mind me usng them)
