ok, 50mm medusa it is then and i can get them from Mike aswell
my feigao on 13/40 gearing clocked at around 40-45mph but 13t pinion is the lowest i can go otherwise the gears cant mesh properly
a little bit more speed would be nice aslong as theres still plenty of power
i want to stick with a 5mm shaft though because i already have all the mod1 pinions
