I know that I should have done that FIRST, before I ever even got close to those cores. Unfortunately I didn't, and I was so bummed to come back the next day and see these thick beads of dried glue running down both sides of the TE. On the back side it was no problem. I was just going to sand it even with the basla anyway, but I have had to cut it out from in front of the leading edge. If you look close you can kind of see it. The sheeting dips down just a touch as it meets the TE. I am hoping that a little putty and a little sanding will even everything out.

This is what I did, tell me if it sounds about right. I sprayed both the TE and the core with a spray bottle and some water, spread a layer of probond over both surfaces with a scrap piece of balsa, let it sit for a couple minutes, give them both another misting and joined them.

I put a good layer on, in thinking back, it was much too thick, from what you said I guess that I need only a very thin layer? Just enough to look wet, huh? Mine looked gooey...

It was nice though, the bond held and set fast enough that I didn't need a million pins, but was easy to move evan after they touched.

Like I said, I was really happy with it before I left for the night, and I an a freak about neatness, I cleaned all of the glue off the balsa and the cores. I hate being able to see glue everywhere, it's a peeve of mine.


The Super 77 is working great, it is the best method so far. I do want to try this probond again, and you're right, I just have to practice.

Anyway, that instruction sheet you put with the cores is great Andrew. I wish that I had it when I did my Mustang wings, your's is so much better than the one they put with the Ace R/C kits. It's kind of funny though, I have a bunch of old Ace kits from the 50's and 60's and they came with that exact same sheet on working with the foam wings, the same one they come with now. You should look into that, maybe they need some help updating...
