honestly, regardless of what anybody else says on the entire web (including rctech), the best RC chassis for drifting is HANDS DOWN the TAMIYA TL-01!!!
cheap, and the BEST drift chassis ever. IT's not pretty to look at, but it's by far the BEST!
i know this from experience. believe it or not, take it or leave it, but i know this is fact.
i even hate to admit it, but it's truth and you can take this to the bank.
