Get some Bob Smith, Devcon, or Great Planes 15 or 30 minute epoxy.
The longer the cure time the better the strength.
5 minute epoxy flat-out sucks. It cures too fast and it's bond strength sucks.
The BEST epoxy around is West System and is available in most marine stores.
West System is NOT available in small quantities and IS expensive. It is mixed in like a 3 to 1 ratio of resin to hardener and does not contain strength-weakening fillers.
Sig used to offer a long-cure epoxy that was almost as good as West System and may have been re-packaged West System in hobbyist quantities. That was mixed in a 3 to 1 ratio also, but naturally is no longer available to my knowledge.
DO NOT USE any brand of 5-minute eposy for ANY model construction.
Make sure you "rough up" the plastic with sandpaper where you will be applying the epoxy. It gives the glue more area to 'bite' into.

, if you have to ask what is "NORMAL" , you probably aren't !

Failure may not be an OPTION, but it is ALWAYS a POSSIBILITY.
ALL systems are GO for MAYHEM, CHAOS, and HAVOC !
