I run a robinson racing slipper with a 66T plastic and 65T steel spur... Somthing BrianG got me thinging it was mentioned that the MGT spur is Mod 1 and fits an emaxx.
Well low and behold - RR do a slipper for the MGT with a 54T spur. An email later and for 18.5 I can have a 54T spur to go on my existing EMAX RR slipper...
Just re-reconfirming it is Mod 1 pitch (99.9999% sure it is as 54T is 56mm diam) but this looks like a very easy way to convert to Mod1 and provide a better range of gearing options...
I have the complete RR mgt kit with the metal spur around somewhere. I will dig it up and take a pic if you like. I never used it, as I converted my emaxx trannys to single speeds and put the revo spec slippers on them.
