I maidened my extra the other day, stiff crosswind but growing impatient I flew anyway. Man this thing is light. Easily took off 1/4- 1/3 throttle. wind was tossing it aroud a bit. Surprised that I needed little to trim it out. Vurtually zero roll with knife edge, although tends to pitch to belly a bit ( I guess that means it is still a little noseheavy). easy unlimited vertical. just starting to try some 3d. Floats and floats on landing. It is a keeper.
Pull Pull working fine. this plane would balance fine with a ys 140.
