Alright, thanks for the rules update, I'm keeping with 2.2 and 12.5 inch WB (it is still 10" right now)

On the battery my thiking is that if it likes the extra weight then it might as well be inside the front tires instead of high up in the chassis, does that make sense?

The worst thing about it is the steering really is no good, I'm using a 80-100 tork servo and all stock linkages.
