When i am building my ARF Avistar, the hinges say to use CA glue, other places i hvae heard you can epoxy them. Is epoxy okay?

Also, my fuel tank doesn't slide all the way up in the slot provided... what can i do about that?

any input would be very helpful!

thanks!


Oh yeah... i heard it's good to fiberglass the wing halves together....
How? i have all the stuff for it, where do i do it etc?
