Ok, I have one with a Saito 100 on it. How do I go about "glassing" the wing joint. I have already experienced looseness in the firewall. I had to go back and coat the interior with epoxy and cloth to firm it up. Like ringram I'll be pissed if the wing fails now.
Often, once a firewall begins feeling loose, you need to pull the firewall out, clean up the joint(s), THEN dowel pin it back into the airplane with epoxy as the glue. It is quite possible it feels fine now... but is just as weak (or weaker) as it was whenyou first mounted the engine (and you thought it was fine for the oversize engine then...)
Patches such as described fail quite often...
