i have just repaired a wing from a sukhoi su31 hobbico and wondering if the fiberglass i used will hold the wing it is very strong and i can put most of my force on the tip of the wing and will not budge. before i broke the plane i put fiberglass cloth on the center section the break away part is just outside of the spar. will this be suitable? also im worried about latteral balance how do i balance latteraly? i have somewhat of an idea this was nothing to do with the crash not to mentionthis plane is not even a week old!!! i put in wrong aileron directions[:@]

Sounds like you did an adequate job. As for Lateral Balance.. Just have to adjust accordingly. 30 minute epoxy and some bb's usually work. If its not that much off, just epoxy is satisfactory. punch a hole big enough to put the tip of a glue applicator in the "light" wingtip. set about putting a little bit in at a time. when its almost there. Stop, let it cure up.fine tune it with even smaller applications of expoxy. when done, simply cut a nice little round patch and cover your hole. Additionally, if this isn't too confusing yet, there will be others coming along with even better ways to lateral balance a plane.
