thanks for the info DTB, did you have any isues with recovering the exposed areas? What technique did you employ in getting it to look clean?
Before I flew my plane, I read all the exploding wing storys on the long Funtana thread here. I knew something was going on or a lot of people didn't know what they were do, but I also knew Bentgear's Funtana was doing fine with no modifications what so ever. I didn't want to take any chances so I dropped thin CA onto all the joints on the LE and where the ribs meet under the sheeting, also on the sheer web area also (front and back). The wing tube area was beefed up also using a little more glue. I mainly used a long extension with a brush on the end to work through the tip and root of the wings. I was able to do all the work needed without removing the top or bottom covering. Every rib has been brushed with thinned epoxy to make sure no cracks were unattended and the servo tray ribs were reinforced with a little glass. These ribs have to be strong IMO and the TE of the rib was resecured also. Be careful of the ribs close to the tip. They all had tiny cracks that you couldn't see through the covering, but once the covering on the tip of the wing was removed, the cracks were there in plain view.
Before the building police comes to arrest me, I'll be the first to admit, this may have been a little over kill even by my standards, but one thing for sure is the wing and servo trays are a lot stronger than they ever were when they left HANGER 9 and obviously did not add much weight as I am still under 9 lbs. If you take this route, the key is to not go crazy with the glues. That stuff adds up weight quick. A little does a lot.
The photo below shows a crack rib on tip of the wing that was not seen through the covering. The photo doesn't show the crack very well, but there was enough space to allow light to pass through when viewing it horizontally.
