Having a various foam arfs we have run out of sky on a few occasions have used
both foam safe CA and 5 minute epoxy ok but no flex hard joint . Home depot and the
hardware stores have gorilla glue this expands slightly on drying sands great and makes a great repair material it is not quick this is for the fix at night and check in the AM due to its expansion thing it fills in the missing small areas very nicely, 6 or 8 oz
is only about $7.My zagi fx was broken in half and missing chunks after the glue almost
set still pliable I used some monokote over it and hand molded the keel back in shape

I'm not exactly certain what you are asking, but GG is excellent for bonding foam.
Most of its weight is contained in the liquid, so that it dries very light.
12 hours should be long enough drying time for any but the worst crashes.

I just did not get around to it until a day later.My slowstick wing had hugh breaks
