The Chipmunk is a 40 size. The only thing I have yet to test is how the E6000 holds up to nitro fuel residue. If need be I can super glue the edges of the plastic just to seal them up. That's probably overkill but once the fuel gets in there it's a mess to repair. By the way, I have a couple of U.S. Aircore coroplast planes and had never thought to try E6000 on them.
