I think the concept is good. But I think RC is wrapped up in its own standards like KV and timing and turns and ...
i think if you want a beginner car you should get a 75 watt motor
if you want a stock class something like 150watt
mod is anything above 300 watts.
every motor you buy outside of RC is rated in power
and the rating is accurate.
you can still measure resistance and ... to insure people aren’t cheating.

brushless motors get more powerful every couple of years and the RC industry hasn’t tapped into most of the tech that will continue to make them more powerful in years to come.
measure these motors in something meaningful and you can control the motor wars.

But I suspect only a couple mfgs have a winding process that can hold a tolerance to make a power rating meaningful. I’m guessing
it really just takes a winding machine that has a couple of servos to make the bends and wraps consistent.
