I have the US 120 (old style) with a Quadra 35 on it. Flew great at 1/2 throttle, but when I opened it up lost the plane due to flutter.
Dumb mistake on my part too light of linkage on the elevator. But while I was flying it did some loops, rolls, ect.. and the balance seemed great and plenty of power. I'am in the process of a rebuild now.
Excuse me...I am running a Master airscrew 18x6 on the Quadra.

I have a 120 size stick, home-built from ply that weighs 17 pounds with the Mac 32cc installed, swinging a 18x10 prop. It has plenty of power, and runs great.....This plane is probably a little heavier than the regular "stick" so you should be fine with an 18x10......See pictures under "frankenstein" link (conversions).
