kyosho 46t spur on CRT

[RC-Monster Mike]

The CRT mount will allow the 46t/11t gearing, but the CR mount is the better option when using the smaller spur(diff rides a lot lower). There was a batch of CRT mounts that was pretty limited on the pinion size when using the 62t spur - looks like you got one. It will work down to about a 9 or 10t with the 46t spur.:)
