I have a Cyclone TC but I wouldn't want to spent that kind of money just to convert it to a drift car... I mean, it's your money, but you can drift as well with a TT01...
I was one of the people that was instrumental in bringing RC Drift to the US (I worked for Super Street magazine and we worked with Yokomo to bring their drift cars here and set up the first official US RC Drift competition back in 2001) and it's all in the suspension and steering setup and the "tires"... although there are some of the newer cars that are specially balanced for drifting with under drive front gearing (or overdrive rears) for full-countersteer drifting... I say buy a drift car, buy a less expensive car that has a drift conversion kit, or buy a less expensive car and just put the drift tires on it, balance it out, firm up the suspension, and go for it
Above all.... have fun
