Lincpimp I was actually going to buy one of the 100A controllers for the Ofna EDF project. Great Planes stuff is very nice so I'm sure it's well worth $120! The card makes it soooooo much easier to program, too. Just don't forget the PiStix adapter.
The brakes will be the std air esc style, not proportional with intensity settings. I would just use mech brakes, check my other new thread about an tmaxx conversion. Should pique your interest!
