Thanks for your help. Actually, I'm from Australia mate I had a look at the EON 33. It does have a very high discharge rate for its size, but they all seem to have small capacitys. I think the 6S2P idea is ambitious too. It will add an enormous amount of weight to the car and also give it a higher COG, but it would be good to run a larger brushless. I want to still keep the 2P config for a higher amp output but after some thought I think I might try 4 2S packs for 4S2P or maybe even only 3S2P for that matter. For the body, I was thinking of sealing it to the chassis (as much as possible) to make a much more aero underside and maybe also a custom body for increased aerodynamics. So for the record I need to stick to production parts you say? Even if the end result still has a perfect 1:18 wheel-base?
