I don't mind helping out a fellow drifter, but your bordering on spam now and what's with quoting your own posts
Your better off doing a search for "RC drifting" and spending the night reading up, as the chassis you want isn't even a TCX any more so posting in the TCX thread will serve no purpose.
One thing i will say though, you will not find a TC-D.
They have been discontinued and are rarer than rocking horse crap.
Ohhhhhhhhh and drift assist
Might better to leave that one out if you post on RC drift forums otherwise they'll rip you a new one
Cheers
Mark
