hello everyone...okay so ive been looking at the mini slashes and the mini revo and wondering how good of a truck/mini car are they......ive seen that they can go 50mph which is very impressive for a mini but my only thing against buying it is its dam battery tray.....its very small cant fit a bigger battery, possibly not a lipo...which makes me mad and you gotta buy the extra 6 cell battery thats only like a 1500mah which doesnt have mich runtime....so really how good of a truck is this? any problems youhave with it? thanks
