Here are some samples of solutions I've used. For a cracked sheet fuselage use TitebondII and pieces of paper grocery bag with the glue wiped on both sides (clean up any slops & spills with water & paper towels. Buy a box of popsicle sticks (like $3 for 500 at a crafts store) and "sister" broken frames with them or pieces of them and epoxy. Coffee filters and thin CA can be used for reenforcing snapped balsa sticks or sheets.

It always pays to think about how best to keep the weight down. Lighter flies better.


I use two kinds of epoxy - 30 minute and finishing resin (like a very thin "two hour" epoxy). I have never been satisfied with the 5 minute epoxy.
