Watching with interest.

How well does that elevon routing work?

It seems like it might bind, but it sure is a clean installation!

No binding. Sullivan flexible nylon control rods. They will handle a 2 1/2 inch radius.

In your pix You have no real torque on your cotroll linckage.
If you get it going fast your servos might pull but you have the wrong geometery to the horns to get them moving .
The flexible rod will bend down and touch the wing top and the controll will be mushy and non existant at medium speeds.
The maxi swift is famous for having these isuues already and your control rod install angles and clevis attached to the bottom hole makes for some possible problems.

What servos are you using?

The Maxie Swift elevator control problem at speed is related to the extremely flexable elevons which bend under stress which is why I glassed mine and they are now very rigid. There is no problem with elevon control at the speeds mine flys. If I wanted something that flys fast this wouldn't have been the first choice. For FPV my goals is primarily slow flight.
The photos shown are of construction and my stuff constantly evolves. I'm not using the bottom control horn holes.

Good ,at the bottom it would be verry poor.

Done in a very stout way it will fly with a much better feel of controll .

I like your landing gear ,thats cool.

Love the pod idea, would be an interesting addition to my Zephyr.
I would be tempted to make the rear wheels individully attached to the airframe to get a bit more width (our field is grass and has a few lumps so width=good)

Love the idea, as a modifiction, could you use the steering servo to also pan the camera while flying ?

On the control rod issue, if you do find you have down flex (my zephyr had that as I forgot to brace the rods), what i have found is make the outer red tube longer so it goes almost all the way to the end of the yellow inner rod, get some PVC tape and tape on one side between the wing and the rod, then use a glue gun, to fill in the area, like building a bridge of glue under the rod, then use a second piece of tape on the otherside to finish the job, you end up with a Tape/glue/Tape sandwich that looks tidy and like you ment to do it from the start :-)
