go to the LHS and ask to have a look at an HPI E10 (drift or touring, both are the same chassis).
it is the WORST TC ever made. But I don't think it would take a 17.5 brushless motor. Mine shredded at the sight of a 19t brushed motor.
NO tuning options. HUGE amounts of chassis flex. You might just be able to get one round the track, and for $50 or whatever for a roller its worth a shot!
