Weekend Therapy

[Regalbeagle]

I did some flying in my legal eagle this weekend. Still dialing in the camera angle with the head mount. Stick with it builders; these machines are pure pleasure.

From Peanut to Fullsize - Kudos, Steve

Always inspiring to see new videos posted and as a builder, it is also an opportunity to see up close and in real time how others have gone about their build.
Congratulations

Great job on the airplane and the video.  Very therapeutic...

[Jim B]

Thanks for the video. Looks like a lot of fun.  I'm looking forward to flying mine, but still a ways off.

Well Done! 

And welcome to the group.

Nice video, very curious on how you did you cabling. elevator, rudder and ailerons, looks like push/pull cables. do you have a build log with pictures?

[Regalbeagle]

Thank you. I stuck with the cables in the plans for the rudder, but I went with a push rod system for the elevator and push / pull cables for the ailerons. I really like the direct feel it gives the controls. 
I sort of kept a build blog. It is missing a lot of the build and some posts got mixed up with a different build. http://notsolegaleagle.blogspot.com

Congratulations! Sweet ride

 Tell us about that seat...looks comfy.

Firestar ultralights use these on their elevator.  The one place you least can afford a failure.
They had failures.  They changed to 2 Teleflex cables.  I am not sure if it is set up to pull-pull or just redundant push-pull. 

The purported problem with Teleflex is, if they are used to move a control horn (lever), the solid end must travel in an arc and this can "work" and eventually break the threaded portion.

The link below instructs one to install the cable to the mid line of the arc the horn will travel to minimize the "working" tendency.

It goes without saying, inspect both ends before every flight...

The seat is a race car seat with a bunch of holes cut in it to lighten it up. Foam over aluminum. Easily the biggest indulgence weight-wise. I figured I could always fall back on the original aluminum strip seat or a fabric one if my weight didn't come out right, but it ended up fine. It's a regular lap of luxury.

The push pull cables were a concern of mine, so I spent a lot of time making sure they were done right. They have ball joint ends and are mounted on their center lines with stops to prevent loading at an unintended angle. I went with shorter control horns to minimize that arcing at the expense of slightly higher control forces. I wouldn't use them on an elevator, just for peace of mind.

I would seem you could mount it such that the plate with the hole where the jamb nuts go could pivot on a bearing.  Then it would appear it would not matter how big the arc is.  The cable could stay straight with the fork end and not cause fatigue.
