It is an excellent plane. An all time favorite of a lot of r/c pilots but not for 3d.

I am building one right now. I wanted to modify it for 3D but its pretty much impossible. This kit was designed a few years before 3d became popular. It is a scale aerobat and thus doesn't have it moments and wing area fudged to make it 3d better. Also the airfoil is optimized for precision aerobatics (clean, sharp snaps) so high alpha flight (Harriers, walls parachutes) will be hard if not impossible.

I will damn sure hover with a YS 110 though!

I moved the hinge line forward 1/2 on the elevator, added 1 to the rear of the rudder. Build light and sand a ton and it should be light enough to be fun.

I have attached a pic of what an Extra that will 3D well looks like. Its from extremeflightrc.com. It is light, big wing area, fat round leading edge airfoil, huge rear flying surfaces. They aren't available just yet but I'm gonna buy one when it is...or maybe the YAK-54 in the same size...
