Good for you Lomcevak! Airplanes you build fly better, and airplane you design always fly best!

Mesae is right regarding the wing incidence. It's largely a guessing game anyhow, but I've had the best results with the wing set slightly positive as he states.

If you set it at 0-0, some airplanes fly tail low which just looks weird. A little positive on the wing, and everything gets back in line where it ought to be.

After some test flights, you could tweak the incidence a bit with shims.

Enjoy the project! Be sure and post some pics of your handiwork.
