with nitro and drifting i would suggest a strong weild maybe, get allu cases, you will need to cram them with stiff clay!!, kyosho do one that is ment to be good, mayb try them..

2wd is a waste of time as the dude above mentioned, ive tried it, and its rubbish,... all the best, if you can drift rwd make a video so we can watch!..

peace!!..
