the motor should be 19,100 rpm. no, it won't hold up against 23k motors, but they're too much for most rally anyway. there are a couple floating around my circle & they always do well @ my rallies. my rally tracks are tight & twisty w/ lots of different tracks surfaces & elevations.
there's a Cartrix dual shaft motor out there that is an FK-180(boxer) & has plenty of power
