And, car ESCs have to be able the extra voltage (above battery voltage) that could be generated during hard braking.
That said, I think it would be easier to add aircraft software to a car ESC than the other way around due to hardware design. Of course, if all ESCs were designed with worst-case scenarios in mind, application wouldn't matter since all bases would be covered. But then cost would be higher and/or physical size would increase and people would complain.  |
I've done it, so why can't a real ESC manufacturer do it. The SPIN 200/300 has plenty of copper to handle the large scale airplane they were meant to power and the layout of the ESCs are very similar to the old Schulze 40.160 and they even use the same MOSFET (Not sure about the new ones). They could've at least given it a try.
