Hi

Dan has just about covered it with his post, I would say as you have driven before a 7.5 would be fine, you could go with 10.5 to start with, but I think you would soon get the hang of it.

off road with 2wd on grass/dirt you want you power delivery as smooth/linear as you can, most boost etc settings can just get you in a muddle.

A couple of good lipos would be fine, you can get away with one but its run, charge,run charge thats not ideal,at least with two you give the one you have just used a chance to cool before charging.

Hope to see you track side
