I can truly empathize with you my friend![&o]

I believe in your case, GP might actually help you if you present your case
and of course...have a receipt.

I totally agree that one joiner might be insufficient for this
wing but, it is a difficult subject to model and I doubt there's any room
for anything that would be of help. The wing is just too thin for anything
else.

Now, the landing gear IS MOST DEFINITELY a bad design. In fact,
I don't even think the original owner even knew of the damage
he did to the joint of the wing. He informed me that there had been a "few rough landings"
and that's when I noticed the seam was split on top... and bottom as the tell tale torn
Monokote suggested (I then glassed the center). Other guys I have recently seen have put a section of thin steel
across the legs to strengthen it. One guy even used a section of hack-saw blade in there!
The WHOLE gear needs to be revised IMO, especially the NG! .
It is a real sore spot on this model. Then again, this is not training gear either.
