Check the wire joiner between the 2 elevator halves to see if they are glued properly.
My Escapade had very little glue there.Do not fly it again until you check it and
make sure it is glued properly. one elevator half may be moving due to not
being glued causing it to roll out of the loop.Here isthe tech notice about it.
