Nex,

If you haven't made it out to the field yet - watch for violent tip stalls. This isn't just at slow speed. I have flown the full sized and several 30-40% Giles and they all have the same "gotcha". Because of the tapered leading edge, the plane snaps nice. If you yank it around the sky - especially with your new and improved elevator surface - drastic change in AOA will make the wind stall fast. The tip will stall first. Told a guy at my club about it - unfortunately, it was after he dirt darted two of them. Of course, a lot of this depends on airfoil - the closer it is to scale, the more temperamental it will be.

I flew the full scale plane for a year in competition and sold it. Now looking at modifying an old Akro to a Laser 200.

Good luck.
