Well... I maidened the Sukhoi today! Pretty par for the course. In line with what others have found, mine needed a little up-elevator trim. As far as side thrust went... perfect! Flew really nice, and precise! CG was a little far back compared to what others quote (about 1 inch behind centre of wing tube), but for me, this felt perfect! Still needed a very slight push of elevator when inverted. Flew on high rates, with maximum throws that the surfaces would allow, and she seemed real nice. Engine leaked fuel on test run, which on the last plane (WH Edge 540T v2) I thought was fuel spitting out of the carb. Anyway, the test run a couple of days ago revealed that the leak was on the crankcase (3W 56iB2 twin). So, yesterday, I pulled the engine out, stripped it, and reassembled with Anaerobic high strength gasket sealant... perfect now!!! I have the carb diaphragm housing vent mod done, whereby the atmospheric pressure vent is extended into the fuselage, with a 35mm film canister... But, neglected to cut out part of the covering film at the rear underside of the plane, so I guess the fuselage was pressurised, causing the engine to hunt a little in the midband. Engine is running on MTW RE2 tuned pipe (was on two canisters in the Edge), and I can't believe how smooth and quiet it runs on the pipe... absolute bliss!!! I expected the plane to slow down a lot for landing, but found she wanted to glide on just like any other??? Real nice though! In all... love it! Oh, had to modify the canopy screw-down blocks, as otherwise, it would have pulled the sides of the fuselage in too far when tightening the screws, and damaged something. Will get pics of this... easy fix!
