read this link with interest, bought the blue one and is still in the box.
what I'm missing in your stories is the second tube in the main wing.
I fly a Xtra 2000 with 26 petrol engine and wanted a more fun plane next to it.
The angle of attack can vary with only one tube and 2 little bolts, specially if they are not tight fit.
My Xtra has two tubes and only one bolt for holding the wing to the fuselage.
In the manual I can not find what the angle should be.

anyone has a clue
