I was going to put my Ballistic 13.5 in it with a 1s LiPo from Promatch, just need some 16 gauge wire and a Novak voltage booster. I thought about getting a LiFe receiver pack but the pack would weigh 40 grams and the booster only weighs 13 or so. I probably won't have the whole thing complete by this Sunday, and as Sunday is Easter it wouldn't matter anyway, but I hope to get it done and that big speed control shoehorned in, balance the rear pod, things like that.
