I have just purchased a second hand Novak Brushless 6.5R for my B4.
The
novak manual recommends a 17-18 pinion for a 81 spur in a B4. I was thinking of the 17 due to the fact ti is a smaller track with many tight turns.
However I have read in a few places that in the B4 that this does not fit and you have to use a different spur.
Is this the case and what set-ups do other people have?
Thanks
