Well I want to get an E-Maxx to race and I want to put my Mamba Max 5700 in it. I think it will be fast enough but Im not sure. With the stock settings, and not so new 3300 my grAPHITE xxx-t can easily flip when pinned when it catches a little traction. I would probably run dual 3300's or maybe a LiPo, so that should make up for the weight in my opinion, an extra battery.So I guess I am concerned it wont be as crazy and fun to drive, strictly because of the added weight, I know a monster truck is completely different handling wise I am talking pure speed and acceleration. What do you think?
