Old thread alert! Recently picked one up cheap which I've now assembled and will test on Sunday. I've had their T4 16-18 conversion based one for a number of years. The arms, hubs etc are all the same hence buying the RO one when I saw it. MTC (Mini Touring Car) as it's called in the UK is finally starting to take off and there have been national events the last few years with numbers increasing each time so I might try some again. Typically run 17.5 blinky with the national series limited to a couple of cheaper motor options and esc (in the Xray one currently)
