OK, your measurements on the stock plane were the same as mine, 2-1/2 degrees postive difference between tailplane and the wing. If I understand you correctly, you took the positive tailplane angle out with the mounting wedge, and you liked it better?

Mine seems to fly OK, with no fussy pitch sensitivity. Although it does take a lot of speed and up elevator to get it unstuck on takeoff as you say.

CG is right on the spar. Maybe Goldberg knows something about the funky airfoil (very small LE radius, entry point way down low right on the flatbottom line) that required a lifting tail to balance... With these popular, high-volume production products you gotta assume they had time to think this stuff though and fix what didn't work right.

I'm just trying to understand it...
