Thanks, I ordered a 46t RC8E spur, I'm happy to let my tyres do the slipping.
which is exactly what I don't want my tires to by doing while on track. But this is supposed to be basher, so it don't have to be fast anywhere else than straight line so I guess you're fine.
Well apart that that slipperential protects you motor after big jumps by slipping and taking all the heat instead of rotor.
