Started sheeting the upper right wing. Edge sanded 4 4"x3/16" sheets, gluing together to form a 16" wide sheet. Marked and trimmed to fit sheet around the ply/balsa TE for the outboard flap. Shown below, I've just glued the sheet along this ply/balsa TE and clamped it flat.
Below, the right wing with upper surface sheeted.
Spent quite a bit of time figuring out how to hold the wing panel in order to build in 1.75 degrees of washout. Turned out, I need not have worried so much. After the glue setup, found that the wing panel could still be twisted a lot. Sheeting a single side did not stiffen the panel has much as I expected. So, I'll fixture the wing panel with the 1.75 degree washout in place, then epoxy the wing tube in place - this will stiffen a portion of the panel - three ribs worth.
After that, I have internal work to complete before I can complete the bottom sheeting, which will fix the washout in place.
Waiting on 50 cal barrels. Need to order offset hinges for ailerons, design/build ailerons and flaps (plans and laser cut parts are for sheet controls - I want fabric covered), make decision on servos and order, decide how complex I'm going to be with lights.
Will sheet the upper left wing, horizontal and vertical stabs.
