wing failure of the balsa f5d
had built 5 balsa f5d but they all crashed by the wing failure......
the wing structure was the combination of 3mm balsa/carbon stripe 0.6*1.0mm spar, 3mm balsa ribs, and 1mm balsa skin, all components were glued together.
is there any buddy can tell me whether i can build a strong enough balsa f5d? or is there anyone had built sucessfully??
how do you guys design yours?? looking forward to you guys.
