Thank you, R.C., the MFA motor and planetary gearbox look perfect if I'm going to follow the steps of the one link you sent me, where the guy on hobby havoc used the drill motor. I just finished up the P3 so this coming weekend I'll be getting started on the 250 and the first step will be to order the differential and the MFA motor/planetary gearbox. Do you think I should go with the 5:1 ratio, or the 100:1? I think the 516:1 would be too slow, don't you think? I'm thinking since it will run through another differential I should get the 5:1, but I'm not sure so your opinion would help. I still have a lot of studying to do!
I'll have to see if I can get that diff he used without having to buy the whole revo. Lots to do, lots to do.
