Some mod's for 2019.
I want to change the tailplane section to a flat plate. The flat plate has the steepest increase of CL, near the theoretical maximum at 2*Π*senα. And the increase is almost a straight line. So damping should be at his best  Roll Eyes Roll Eyes Tongue

Structure is made with a 2,5mm carbon tube as LE and balsa strips as spar and ribs, carbon covered. Weight 4,8g as the old one.

Now I have only to go to the flying field and fly....

Urs,
I've tried flat plate tailplanes several times with F1B and never saw any superior damping features. I always went back to a standard flat bottom (or slightly undercambered) airfoil.
Let us know what you feel happens with your model!
