Rs4 mt2 help
I have an rs4 mt2 with the g3.0 nitro engine and single speed gear box. I would like to know the pitch of the spur gear as im looking to convert to electric and need to get a pinion gear. Ive searched everywhere and cant find what the pitch is for a single speed truck.

spur gear
Ok so I got the gear pitch figurred out, its a mod1. I installed it and ran the truck, its going to be quite fast with the 17t motor I just need a battery that can push it as the one I have doesnt have the stones. I have a 2s 5000mah lipo on order.

I need some help with the differentials though. The outdrives on the ring gear side both front and rear are very loose. I pulled them apart and the gears all look good with no teeth issues. I tried a thicker oring and while it got rid of the play it made them hard to turn. Is there a bearing in the ring gear? There doesnt appear to be. Is there a rebuild kit? Does any one have any suggestions to keep this old truck going?

Thanks for any input.
