Got a CA tip from a balsa and tissue guy. BEFORE you start working on your plane apply a thick coat of CA to you finger tips and let it dry then proceed with the build. For some dang reason when you intentionally put the glue on your fingers it is much easier to peel off, don't ask me why but it works
That AgriDuck is one ridiculous airplane...too cool, I might have to see if an come up with a scratchie like that, what power combo is it running? I don't think I have a motor that will swing a prop like that.
