I put 6 flights on my Sukhoi before I dumb-thumbed it. Flew allright with an OS61FX, but not much vertical performance.

First flight was a real handfull. Even with carefull building and balancing it was extremely out of trim. Highly pitch sensitive and rolling hard left. After getting it trimmed out I really liked it. Landings were very fast at the recommended CG. I added 3 onces of lead to the tail, and the airplane finally slowed down on landings. I stuffed it after making a stupid mistake on high rates with way too much expo.

Build quality is average.

I've since rebuilt it, and have mounted a supertigre G90. First flight with new engine should be this coming weekend.
