Hmm, RC brushless motors normally only need two of the three wires between the motor and ESC swapping to reverse.

Yes - that’s certainly true for UNSENSORED brushless motors of which I have many, and a fair bit of experience using them in the world of aero-modelling.

But here we are talking SENSORED brushless motors which at the very least would require the Hall sensor signals to be re-ordered to match. But for what is known as trapeizoidal waveform drive it appears even more complicated as the sensor positions need to account for a 45 degree offset which is different for each direction of rotation.

Maybe all of this is handled in the ESC in R/C cars as per your experience Kevan?
