In fly the ZDZ 40 was a noticeable having harder time in the up lines. Vertical eight was a clear problem.

That's interesting, as the ZDZ should make a solid 20+lb of static thrust with the pipe and that should be LOTS to haul an 11lb aircraft around. I would bet that prop selection would sort that out.
There shouldn't be a 22oz difference between the OS160 and the ZDZ if they are both optimized, that seems way too much to me. Do you have a breakdown of where the weight is?
Dick Hanson would argue that point about the soft mount and gas engine combo. I plan to solid mount a gasser on my Pentathlon if that is what I settle on. We'll see what happens...
Depends who you talk to.. Chip hyde swears by none. Mixes rudder in. He makes a decent point. Not sure I'm buying though..

Funny guy, Chris.

I WAS speaking of thrust as in the force that moves the aircraft through the air, not RIGHT thrust. I haven't worried about the trimming part yet...
