Jan 01, 2019 Midwest super stearman parts and info I picked one of these up a few months back at the atoms RC swap meet for dirt cheap. It's beautifully built and covered( albiet with some hanger rash) with a saito.91 and what seems like 3 lbs of lead on the nose.

I agree with Flicka - The best way to reach the right CG is to save weight in the back of the plane. I regret a little that I didn't change the balsa block in the rear end to somthing lighter.
As I wrote in an earlier reply, I have 500 g lead hanging below the engine mounth, plus the quit heavy Dubro damped mounth, which give a total close to the 30 Oz. The manual says 20 Oz.
Regarding the choice of engine - I did by a second hand OS FT160 for the Stearman. A beautiful engine (What a sound!). My argument was - Why put lead in the nose, when I can put in a nice engine instead. But when I saw my Buddy's Stearman with the TT.91 fourstroke I changed my mind. The Stearman is not a construction which need this oversized engines. I don't know how much power the YS 1.20 engine has, but you have to be careful not to overload the Stearman. I own a YS .91AC as well and it is indeed a more powerful series of engine than the OS.
By the way, I have been wondering about the travel of the elevator. The manual says 1' up and 7/16' down at high rate?
This is my first biplane - I this normal on bipe? All the monoplane I'v build is trimmed with symmetrical travel.
