Ok, yesterday the first flight was done (or almost done!) The setup of the triplane was: 2 º the upper, 1ª the middle, and 0 the lowest wing. But the wind took his power over the airplane: the triplane took speed, and the model went to left, and the right wing lift of and the model flips over. The 2 mm ply struts of the upper wing broke. (I think 2 mm ply is not enough to support a 1, 30 mts wing). I’ll report after the first success flight what happened.
