Of course the test fitting of the top wing was easy and without issue---so much so that I skipped the jig and went right after it the old-fashioned way, after I had added the windscreen and attached the rigging lines to the bottom of the top wing.

Ruh-rho! Another hair-raising adventure in upper wing attachment! I'd fix one side, and the other would pop out.

Shoulda used the jig, dummy!

Nonetheless, after several rounds of push, shove, re-adjust and push some more, the top wing is now in place, firmly I hope, and everything seems to line up closely enough.

I'll start stringing the rigging tonight.

I've been spoiled for wing attachment by WNW, where adding the top wing is like gluing on the propeller.

No pix this time, as it looks just like the test-fit photos. Getting close to calling this one done!

Bob
