Another hv air esc, might be worth a look?
 

Here is the new Great Planes hv air esc. Good to 12s lipo and can be programmed via a prog card.

So whatcha think?

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.

What's the "brake" like on those?

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!
