3W 75, 85 B2, or BME 102/105 for the H9 Sukhoi??
You can certainly get unlimited performance with a ZDZ80 on this bird; a buddy's has awesome vertical with a standard muffler and a Menz 26x10 - vertical is similar to another one I saw fly with a BME 102 (not sure which prop on that one). I imagine with a tuned system the ZDZ80 would do even better.
I know it wasn't one of the choices mentioned but it still is a great combo for this plane.
