Some great info on this thread, I might add the ca has gotten to me over the years as I used it to much to often.... now it screws up my breathing almost instantly ...for days...so be careful ! I was sanding a kit I bought that was framed up...ten years ago, after just a little sanding, bang I could taste/smell that crap in the air , just like it was fresh fumes...

On another note I LOVE the Gorilla /Elmers ultimate glue... Just don't use it where you will need to sand..I like to paint it in joints with a cheap brush or q-tip after using white glues or the foam safe ca's (don't bother me ,don't work as well)

Also on arfs stand the fuse on the nose when its new, drip gorilla /Ultimate down in there , paint it in all the joints... that sucker will be strong now! I also stand the wings up and I paint down in there EVERYWHERE I can get through the root of the wing ( hook a small epoxy brush on a dowel) and servo bays ETC. believe me I think it strengthens them up alot...

I treat every ARF like the guy that built it hates me, I assume the worst and try to make it as good as kitbuilt...

Its all anoying to do, but I have been putting gas motors on things they wern't supposed to be on ,with no structural failure yet! fingers crossed...
