If you have the aluminium spar system, then it is one of the latest versions.
The early ones had a wood spar arrangement that got fuel soaked with the Byron fan and would fail after a few years.

That aluminium spar system is strong enough for the turbine, too.
All the TGA jets use the same style of wing attachment. They are plenty strong.

Don't add 3/32 balsa sheeting to the wing, that will change the airfoil. Just do the .014x1/2" cf strip I mentioned in the earler post and then cover with cf tissue/ 2oz glass and epoxy (Both in the same coat.

See my web site for a method of doing all in the same operation. It is the lightest glass system, too.

Oh, and I would still make the wings removable. Saves a bunch of hanger rash, and repairs are easier to do.

Have fun!!!
