Taking Dehidral out of a wing....
 

I have a "spare" wing for my Kadet LT-40 (sadly.....I do not have a useable spare fusalage:D)

Would love to take the dehedral out of the wing for future LT-40 updates.....

is it as simple as cutting the wing halves apart and then gluing together again with spacer??

Any quick thoughts on a good way to do this>>?

TIA

You can carefully cut the wing panels apart and, after rejoining them, add substantial plywood braces on both sides of the main spars. Use aircraft ply, not Lite-Ply, and epoxy adhesive.

If it's an allready completed wing, the task is much more dificult. I'd probably separate the halves, and drill or dremel out the "epoxied in" joiners and add dowl rod or fabricate a new joiner. After I got the dihedral where I wanted, I'd epoxy that in and glass the center all the way around for additional insurance. I'd use 30 min. for both steps.

I have changed the dihedral on numerous wings and built numerous foam wings, all without a dihedral brace.

If you have a table saw or radial arm saw, cut the wing in two and trim the ends square.
If you have completely cut away the center rib, cut out a rib for each side and glue in place.
Butt glue them together on a flat surface with 5-minute epoxy.
Peel back the covering and cover the center section with 6-ounce/heavy weight fiberglass cloth and 30-minute epoxy.
Replace the covering and fly.

I do the same as MR. Moorman. When I first designed the one in my avatar, I built the wing to flat. When I gave right rudder, it turn left. Iput the wing through the bandsaw, put 1 in. dihedral under each wing. Glassed it with two layers of 6 oz. glass cloth and all was well.

I use a flat "dihedral" brace of 1/4" spruce glued to the old cut-off brace, & after glueing the wing halves back together (with a balsa wedge to fill the gap), I reinforce the joint with 1/32 balsa sheet glued on, top and bottom, cross-grained to the joint. Never ever had a wing break despite very violent flying.
