My 3, the yellow one is a standard m03, just sits on the shelf. The copper one is a 4x4 ABC chassis, running a 9turn, currently needing some parts after hitting a dropped kerb at full chat . Orange and black one is the tramp lol, my main runner car, I had a tt-01 for a while and spent loads on it, then realised I prefered the mini! Its a m03 r (the one that comes with all the blue bits) but has various plastics replacing some of the alloy, as I found it needs some flex, has carbon gear spindles, ballraced, mantaray ball diff, 11 turn motor, carbon quick release battery kit, and a few other bits. Its much more battered now lol,l and has new wheels as the chrome ones finally started splitting. Goes thru tyres a bit too lol.
