Ive been looking at them a bit. Thing is, to get something of the power I would need it is significantly larger, more expensive, and uglier than a couple brushless rc motors.
Also, I'm not really needing the reliability of a EV motor. The duty cycle is quite low for a setup like this. It will run hard for maybe 10 seconds tops, then have some rest time. On an autocross track it will run hard for maybe 3 seconds, then every 10 seconds have a couple seconds of running hard. Or at least that is the case with the tracks I typically run on.
Beyond that, it isn't like these r/c motors have bad reliability. The motors themselves are pretty simple. The way they are built the only things that can really wear out are the bearings. They don't have brushes or communicator like a traditional DC motor. As long as you don't overheat them there isn't much to worry about.
