KR> KR1B motorglider criteria question

I can't argue with that...I was just wagging it because wiki says 34 lbs. Still, a very good looking selection for the purpose. I think I have figured why the faa has that criteria. I think they are combining surface loading and aspect ratio...both use wing surface...just a guess.of course...but

The goal with a self launched sailplane is glideslope and low stall speed...so high aspect ratio and low weight. The engine we selected back in '82 was a kfm 107...25 hp at 40 lbs. You could do a max gross of under 500 lbs with an engine like that. https://sites.google.com/site/mykr2stretch/ htt
