I always thought it was just as simple as changing the software.

Well, it's the hardware on the control board that isn't compatible with the car software.
I designed the airplane controllers before the car controllers, and the car controller have some SERIOUS advancements over the airplane controllers in the sensitivity of the back-EMF circuit. (there is a patent on it too -- just got finalized.)

So the car software just won't work on the airplane hardware -- different type of back-EMF sensing.
To run car software on the airplane power boards, I'd have to design a new control board for them.
But airplane power boards are really designed for airplanes - - not for the types of loads that cars put on a controller -- our car controllers ALSO use very heavy copper (6/6 on the MM, 6/6 + 4/3 on the MMM) but are designed to handle short term overload currents better than the airplane controllers. The MMM has the same number of FETs as the Phx-80, but handles over double the surge current and over double the continuous current. Part of that difference is the fan/heatsink, but the majority is the copper layout and current path copper total. The Phx-80 was designed to be light weight and compact, the MMM was designed to handle serious current surge and power.
