I had to. Stripped the wing and used 2 oz glass top and bottom on the center section out to the nacells. The wing had stress cracks in the sheet when I uncovered it. Put in dual aileron servos and wider ailerons (1.5" instead of 1"). Got rid of all the plastic on the wing and used balsa block, got 2 extra inches of wingspan doing that. Tri-angle stock around the fire wall. Both firewalls were coming loose. Recovered with solartex and rustoleum paint. Holds up much better. At this time the fuse is still stock, but have plans for that too. Replace the pushrods with steel rod in tubes, and put on an extra style rudder, replace all the plastic, build up a glass nose, then recover with solartex. Others in this area have put retracts on and three engines. I passed on that cause I wanted to get back in the air asap.
