Yes Rick, I think the bottom example is the way Leonard drew it (except the strut would shift to the left, but I knew what you meant)... Either way would probably work (the OCD in my brain likes the top one) BUT that wasn't you original question... If your really concerned, you could always call Leonard... (It'd be a good excuses to talk to the man, lol)  Hope that helps...

Thank you Chuck for reviewing very closely, the tell was your catch of my mistake with location to strut brace from the root where is should go the first hole on fitting.

I used to read a lot of blueprint not create them . . . but no excuse.

I do think I'm going with the top one.

Greatly appreciated.

Pappy,

I was lucky to have talked to Leonard back in August regarding tail sections. He was very helpful, he also let me know he had just started another plane built . . . forget the name, but not his design. Just incredible at 101 years, so I don't want to interrupt his progress!

I just found another reason while laying out on the table to go with the top layout posted. I don't know about the XL, but on the plans for LEU Leonard calls for an aileron length of 73.25". The top layout if my math is correct is just under 75", bottom layout is 2" longer at just under 77".

If you don't mind me asking, how long are the XL's ailerons?

Thank you for being so helpful.

IMHO there is no way an aileron length dimension should be shown on the plans. The correct aileron length on the LEU or XL is the distance between the wing ribs with the aileron hinge blocks minus the clearance you desire between the aileron end ribs and the adjacent wing ribs. On an XL that would be the distance between rib #7 and rib #12, minus clearances for fabric & aileron control horn. On an LEU that should be between ribs #6 and Rib #11. This is counting ribs individually, not counting the two inboard & two outboard ribs as single ribs.
