At least he has not mentioned transitioning to a wing warp design! It works for birds and the Wright Brothers.
Honestly, I hope he gets this figured out and ?succeeds? without a fatality. However, I see way too many unnecessary bends in the flight control path. My fear is he will find out what plastic and cabling can do when they rub together. It will actually take materiel off the control cable. Seizing up was already noted.

The inner sleeve is metal.

His sleeve looks like conduit I’d find at Home Depot with a plastic sheath on the outer diameter.

He needs to take the slop out of the cables. I’m no engineer but he keeps on trying to do so with composite pulley brackets (flex) attached to a skin (flex). A number of AEs keep employing him to use properly tensioned high quality cable in the comment section.

Given all the rest of the design problems, he might already have a warping wing, just not one that can be controlled.

If i were going to use push pull cables, it would be these.
I have them on my boat , smooth and no slop.

Ever had a frozen throttle or mixture cable? Especially in an airplane intended for higher altitudes and lower temps where condensation during descent is an issue.

Push-pull cables for flight controls are for ultralights, that people other than me are flying.

If i were thinking fly by wire, i would try to figure out how to modify a dual stec 3100 system with his sloppy ass cables as an emergency back up.
At ga tech, we used to say “yesterday i could not spell injiner, now i are one.”

Cables like these are used on the Velocity. Not sure if Velocity uses Morse, Teleflex or a different brand. But mine work fine and I haven’t heard anyone mention them freezing in cold weather.

Here are screen shots from his video of the forward and aft pulley assemblies. It seems that a design change that connected the assembly to additional surfaces, either above or to the side, could provide the additional rigidity required. He doesn't show enough of the interior structure to determine if there are suitable attach points near the existing pulleys but it is clear that mounting to just the single flexible fiberglass surface has not worked well.
