I do like those Irwin deep throat clamps - and even though it hurts my OCD little brain to see them all lined up, I have several different makes of clamps in the shop cause each one works better in one particular scenario compared to the others.
And yeah, I pinned the hell out of that sheet :black_eyed:
So the story behind that is once I had the front edge in place I squirted some glue and put a little weight on the sheeting. And then I noticed it was still bowing up in the middle - it didn't want to lay smooth against the rib. So I added a couple pins. And it still resisted. So I just kept going. About half a pack of pins went into it, but it stayed flat at the end.
I got smarter on the second wing panel - I sprayed the top of the sheeting with a little ammonia. It immediately curled down to the ribs, and when I added a little weight to keep it there it stayed flat. So I'll let that dry about 12 hours or so, and it should glue up nicely tonight without the aggressive acupuncture.
Here's the Voodoo Wing after pin removal, and with a nice access hole drilled to get the servo wires down into the fuselage. Important to drill this before adding the final piece of sheeting.
And here's the last of the sheeting on that panel. This one behaved nicely under some weight - I tested first - so no ammonia spray and two day process. However I did get the bottom edge trimmed a little off from the trailing edge block so I'll be coming back with some balsa filler to clean that joint up.
While I'm at it, I'll fill in that huge gap around the half-round register bump that is supposed to line up the trailing edge pieces. I say 'supposed to line up' cause the cuts seem to have been made with a different radius in each piece.
Gotta say, I was happy with the kit quality for the fuselage and tail pieces, but not impressed at all with the cuts for the wing.
