in the attached pics was the last crashed wing, the plane named yoga. 0.9m length and 1.44m for span, the foil was mh32 and flight weight was about 600 grams, powered by a 3000kv h2218 outer tuner heli motor, 4.75*4.75 apc prop.
the spar was glued with balsa wall in the center and carbon stripes bars, like the pics show.
crashed into pieces because of losing control.
i test the same spar with sports on each sides away from 35 cm from the center point, applied 4kg load at the center with no failure. so about how many Gs it can carry can we say?? or upto what speed it can handle if i'll replace more powerful motor?
