As long as you are programming specific motor profiles, any chance of 
adding one for the E-20 motor? It uses a sep-ex motor like the E-15, but

slightly larger. It would take the fun out of having an E-20 to have it 
limited to E-15 power levels by the controller.

And while on a roll, maybe profile the E-12 motor, which was a bit
smaller?

Not that I have any motor curves to offer, but hopefully someone does.
