I have a Brisson 3.2 on my highly modified Stinger 120. Yes, it is a vertical animal, but not a good 3-d plane so far, with the extra wing loading. I'm still tweaking though.

I have a friend who flies a ZDZ40 on an Ultra Stick. That is the motor I would use if I did it over. Almosst as much power, smaller, lighter engine.
