Like i have told other get a center spool (solid shaft
) and run a revo adapter. Run any gearing you want.
Oh, so I was searching the FB group, looking for my conversation with Mike, and found a thread on the Intigy spurs - Apperently they make a 38t and 40t spur for the HP apache that bolts up to the Arrma Center diff!
Added to my tower wishlist...
I ordered one too. Should be here maybe the 18th... also got a 22t pinion.
