Default Surface Mount Fins

Just ordered a LOC Starfighter which has surface mount fins(wings) I think. Can anyone point me to articles about strengthening surface mount fins. I'm hoping to push this bird hard with full G impulse. Hard and fast.

Thanks in advance.

Use epoxy; not 5 minute either. Use at least "15 minute", better yet 30 minute.
Drill 1/16 holes into the body tube spaced 1/2" apart along the fin mounting lines before mounting the fins.
These holes form "rivets" locking the fins to the tube.
Fillet the fins with epoxy.
It will survive on any G motor short of the G669 Warp-9 Aerotech load.

I surface mounted mine using 30 min epoxy. It's been launched at least 6 times without issue, the largest engine's being an Aerotech G40-10.
That gave it it's best flight!
