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.

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.

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

I had one of these cables freeze up on a Citation. scary.

Push-pull cables for flight controls are for ultralights, that people other than me are flying. Those marine cables are 3/8 diameter, they do not resemble throttle or mixture cable which Are Anout .07 and very whippy. I am not advocating push pull, in fact if i were going to do it i would use the cables as pull only as on the boat. The pull side is always in tension which pretty much erases free play. And the minimum curve radius is 4” which he should not have to come near.
I am saying if someone is trying push pull the marine cables would be the way to go, they are all stainless steel and permanently lubed.

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.”

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

The FBW system should be easy. A couple of linear actuators, a raspberry pi and a Bluetooth connection to the accelerometers on an iPad and you're done. Don't even need the side controls, just the iPad.
