Engine for H9 1/3 Sukhoi
ZDZ 80 single.
The CG issue has been resolved by Horizon. They now say 11/16 behind the wing tube.
I'd think you'd be close to that with the 80 single.
Sure a DA-100 has more power but is the extra weight on the airframe worth it?
These planes fly good because of thier light wing loading. Not excess power.
Keep the plane as light as possible.
My H9 Cap weighs 23.5 and the ZDZ 80 single is WAY more than it needs for any 3D maneuver.
Excluding hovering maneuvers how much power is needed for 3D? Not as much as most people think.
Just my .02
