I built my KT with the works every upgrade that Bob had at ETO for it after finding out that the Impact 18 tooth sprockets suck I tried Kenny Kongs 18 tooth sprocket for Bob and it fixed that problem and now it even runs well on gravel .
Its mean looking with no fenders on it and is heavy .
My tamiya Panther is a great runner also added the parts that needed upgraded for it also not as many as the KT .
