Thanks for your = info. I did contact Craig Catto and here is his = response:

Hello = Tom,

That is going = to be quite a challenge to fit.   We make them for the = 540
Berkut, and that is about = a 285mph aircraft and have done one for a
E-racer turbo 540 at 350HP doing over = 300mph.

I do not think = I want to challenge the auto conversion, just the = power
curve many times seems = hard to fit. We know the curve of the Lyc = engine

applications.  Easiest way for you to fit it is = probably with a MT.

All the = best,
