First off I know that I am pushing this airframe too hard and am running a little heavy. My latest desire is putting landing gear on my TT. What I had on hand was a spare bracket for my apprentice with thin 1.5 inch wheels with an 800mah 3s. The first flight folded the wing at the center due to the thin spars not holding. I fixed this by joining the two center spars on either side of a bbq skewer. The second flight was met with the wing snapping at the servo cutouts.
I’m thinking of using a skewer taped down with fiber mesh packing tape but before I sacrifice my newly built nose/power pod, what have others tried that worked?
Firstly you do not mention if you are using a FT supplied kit or if you are scratch building. If you are one who cuts out their own pieces you could try a different and higher lift wing for the TT such as can be found here:

That wing was designed with much higher lift in mind!
If you wish to use the original design wing the first thing I would recommend is that you change the spar from a flat piece of FB to a couple of vertically fitted, (paper on the spar runs from top of wing to bottom) this improves wing rigidity. In addition I would fit a piece of paddle pop stick on the underside of the wing LE centrally so that the wing incidence angle is increased or the front of the wing sits a little higher for a little more lift.
As for the normal wing snapping you could bury a few lengths of BBQ skewer in the wing LE fold.
With every beginner wing I build I run cloth reinforced tape along the wing LE as this tends to allow the wing LE to crease without tearing in most impacts, (including poles and fences).
The servo cutouts do not need to be made and the servos do not need to be fitted exactly where the original design recommended. You can fit the servos at the outer edge of the wing bottom panel and use servo extension leads to extend the servos so the leads still exit the wing at the central hole in the wing underside. Best done with an alternate Spar of course!
The wing joint will not support a very heavy TT long term and it will fail eventually. I recommend that you cut down a paddle pop stick and use it as a dihedral brace or perhaps two.
With the landing gear you can fit almost anything with weight being the only real issue to be concerned about!
For your perusal the following link will give you a list of mods or changes to the TT where you can find what others have done to overcome various issues with the TT.
