Larry,
We have a couple people that respond under this account, and when it's a bit more than a simple support issue we do tend to use our names, but we aren't in the habit of doing that always. No particularly solid logic in when we do and when we don't.
We appreciate the feedback. We'll try to do better.

So, does the Dynon AP servo see load on the control surface to automatic send trim inputs, and do all the trim wires to to the dynon and then the hat sw?

I have a drawing if you want to see where all the wires go and what color. It's based on Ray Allen servos and Tosten grip. Send me an e-mail.
I don't know how it senses but every wire goes to a Dynon pin. Hat switch wires and trim wires. I assume since it controls the hat switch inputs, minor adjustments are initiated by the EFIS.

The Dynon auto-trim is a good reason to use the Skyview system versus the VP-X system, especially if you are using the Skyview auto-pilot. It was not to difficult to rewire to the Skyview system if you have already wired it to the VP-X. In my case though, my aircraft is still under construction and the front skin is not in place.

Bret,
The Dynon Servos do as you say- they detect the load on the controls when the AP is engaged and flying the plane.
All the wires from your trim switches individually go to the AP control panel, as well as the two motor wires from the trim servo. Trim position wires still go to our EMS unit or the VP-X.

Ian (thanks for signing)
Is there any benefit or down side to running position wires to the EMS? At the very least it seems like it would keep things neater. All the trim wires are going to a Dynon box.
Next question
Any benefits over VP-X for flap control? Given the higher load, I would prefer them on a VP-X circuit.

If I am not using the Dynon AP control, is there any benefit in wiring the trim to the EMS or EFIS? I like the idea of auto-trim but the AP control is apparently required to use this feature.

VP position on this is to run the trims through the Dynon for position input and power through the VPX for circuit protection. The Dynon support guys are great and I'm glad to see Ian has jumped on this. My apologies for being late to the thread.

Larry,
We'd suggest the trim wires to the EMS not the VP-X if you are using the Dynon for trim. Just cleaner and simpler overall.
The VP-X flap control is probably superior to anything Dynon can do right now.
Raymo,
There's no place to wire your trim motors to the Dynon systems without the AP control panel.

I have both SV with AP and VPX. As the Dynon chap said, use the SV interface. Ive also got the separate SV AP module and wiring the trim hat switches to this was a breeze.
