My wing is going to have a higher aspect ratio than most...with a 25 foot span. The spar chords have been beefed up significantly so it will be heavier...I didn't design it but I checked it and the logic is sound. It could handle the standard kr2 extensions to make it longer than 25 feet, but then I would be concerned about where the WAFs mount to the wing. I think the toughest part of an lsa would be getting the weight down. Also, when I talked to the faa guy he said that a lsa has to be 100% built per plans at signoff...it seems like the KR community might have a tough time conforming to that standard.
