Physics is consistent, I'll give it that...

Well, yesterday I flew the ASK 2100 power glider, and landed her with the spoilerons with good speed, and she landed sweet with remarkable sink. I am also aware that she will tip stall like crazy. And I know that if you want to tip stall more spectacularly use spoilerons at stall speed. So what did I think would happen if I made my approach at just above stall speed and tripped the spoilerons, especially after I saw her do it twice at altitude while slow flying today. She tip stalled and dropped like a rock right on her nose...


Despite a fairly high speed spinning crash she came away pretty well. The nose is cracked on both sides as can be seen here, with a little foam squish. The motor and motor mount are fine. The long canopy snapped on the foam part. Epoxied everything back together easily. Good as new!

I tried a carbon fiber spar in place of the aluminum spar, which of course had no dihedral. The aircraft flew much better for being lighter and didn't seem affected by the loss of the dihedral. But on flaring for a landing the spar snapped and she dropped to the ground in a semi controlled landing. I put the aluminum spar back on and curiously, she still flew well! Today she flew more stably than she did yesterday. Conditions were much, much calmer. Flew her several times and she was a pleasure! And then I tried to defy physics...

Tomorrow is supposed to be an even better day! I am nervous because I plan to maiden the Hangar 9 Sopwith!
