There are other ways to do this rather than double wires. They are just to keep the wing from twisting with the ailerons moved out to the tip.

I’m working on this right now with my wings, what are some other ways to keep the wing from twisting? I’m not able to double up drag wires without moving ribs around on my wing.

A couple ways ............You can use an N strut similar to what is at the strut attach fitting or something like in this pic. Co-locate structure with the last hinge point. It transfers the rear spar "twisting" forces to the front spar.

Thank you for the photos, I planned to do it similar to what you did. The N strut is a great idea as well!

What are you using for drag wires in between the compression struts? In the picture it looks like tubing rather than a wire.
Also what is the drag wire anchored on since there is no compression strut out the outboard end of the drag wire connection to the spar?
BIG rear door in the fuselage. Is the vertical tube where the flap cable goes up the back of the baggage area removed and truss built around the opening?

The first bay has the drag tube same as a Super Cub. The next 2 bays are #10 wires. The spars are 15" longer than the original spar length ........ so still a "short wing" ............The small tube at the end is a short drag brace from the last set of wires to almost the tip rib that's not yet installed. Not much drag at the tip. No tip bow just a Hoerner type tip. Flap controls are all over head. The rear doors are patterned after the Maule, I just put them on the left "port" side.
