Agreed on the balsa over the foam. Easy fix now. I used balsa as my flaperon tips as well. Aircraft spruce has balsa blocks. 2"x 2"x 36"
Thanks for the nugget of info on the Moisture Minder EDV. Just what I need!

I second balsa. It shapes really good and will hold up much better. Order some superfill. Shape the balsa ruff then fill in holes and gaps with superfill.

So it looks like I will need to undo the bond that holds the foam pieces. What would be the most efficient way? Solvent? Brute force?

I used expanding foam, Hysol, then Superfil, worked fantastic.

Thanks, all! I did some running around today and procured some balsa blocks at a hobby shop.
Brett, that’s a beautiful job you did on your tips!!
I ripped off all the foam pieces and sanded away as much Hysol as possible with a Dremel tool. I am getting a small band saw in few days so I am going to work on the balsa blocks with it then. I think band saw would be a handy tool to have through out my build.

Thanks! Those tips require a lot of finishing. The balsa sands down fast so easy going as you get close to your profile.
Any flaws will be noticed through the covering.
I did not have a band saw and finally caved when it was time for the tips.
So much nicer to have one and I use it all the time for other projects.
