[ScorpiusWireless]

It would be a pretty deep project overall and I already have enough on. It would be interesting though. 
The MPD was kept single sided so all the extra BLDC components could go on side B. We have BEMF detection circuitry in place on the MPD, however it would need to be duplicated again on side B specifically to suit the brief.
Brakes and throttle map are in the Scorpius throttle. Frequency and timing could be set using the app.

You could also place a hall sensor on the brushless motor and plug it into one of the data ports on the MPD to detect timing pulses. I suspect the firmware for this would be pretty deep though with a lot of trial and error work (read time), but would be pretty cool.
It’s also technically possible to analyse the various aspects of the motor, ie torque, power, revs using the MPDs BEMF detection and perhaps the hall sensor could find a role also, ie wheel sensor. 
So the MPDs potential diagnostic capabilities could one day be useful in testing and configuring the system to help speed up development.
The day will come where brushless become the norm and such a chip will be required. When that time will be is still unclear.
