Family down for the weekend so only had time to work on it for a few minutes. Took a pic of the wing in a pretty sad state as it has been cut open and hogged. Even with that, now that I know where the flap hinges will sit have to get in there to install some anchor points. Not sure if it will simply be easier to cut back the skin and patch it later.

The covering will be a patch job, as well for now as I will only invest in a complete redo if this proves to work.

I'll try and post some more pics soon.
