Skyview or VP-X for flap and trim control
I'm out of town so spare time is being used working on wiring diagrams. I'm drawing the trim diagram and have some questions.
1. Skyview and Vertical Power both have controllers for flap and trim. Which do you prefer of maybe a combination. Why?
I would like both flap and trim position on the Skyview MFD. Runaway protection is also preferred but I think both have the capability.
2. Where did you connect the wires? Trim servo has two whites, orange, blue and green.
I'm pretty sure the whites are switched such as the hat switch on the stick. I think I know where they would go on the VP-X. I'm not clear how the other three connect to the VP-X or Skyview.
Drawings would be appreciated.

I'm not that familiar with the Skyview screens. Do they also control the speed of the flaps, or at what speed they can be deployed? That is one of the key advantages for the VPX.
I have AFS 4500s. The VPX controls the flaps and trim. Then passes the position information to the EFIS, wich replays the current state of both on the screen.
Hopefully, the same is true with Skyview.

I am controlling mine with VPX and its working good so far (only 9 hrs). The only thing is, when I trim in cruise, I just barely bump my coolie hat and sometimes its to much. I could slow the trim speed down to reduce the sensitivity but when I'm doing touch and goes, I need it to be fast to go from landing config to take off config. Not sure if using Skyview would help this....... I really like controlling the flaps thru the VPX cause I can set it to stop at three degree settings and then return to home with one press of the button.

Can't remember how to get to it, I think in the "configuration" software but you can set an airspeed at which the trim sensitivity changes. For example I think I have mine set to 100% below 100mph, above is like 50% or less.
I have found no difference in hooking it to the vox or dynon, I hooked it to the dynon. If I ever upgrade the Efis it's less wires is the only advantage. Either way will display on your trim indicator or vs screen or both if you wire it up that way. With the vpx and dynon you will need a position sensor to get the full function from the flaps that the vpx has available. I bought one but haven't hooked it up yet, it's so easy to look out the window. All I'm missing out on is an in-cockpit indication and the single button push full up feature and the single press stop points that you can set to whatever you want, up to four stops I think.

Starts on pages 55 of the VP-X install manual. Section 6.12 Trim configuration and 6.13 Flap configuration.

I don't plan to have it tied to either (VP-X is too expensive and Dynon not convenient).
I'm using the coolie hat on my Infinity grips, along with this 3 axis trim relay.
After flying a bit, I may opt for a speed controller to slow the trim action and disable flaps above a certain speed.

Wiring
I found it. Wire pin outs are on page 33-34 of the VP-X manual.

The trim controller in SkyView:
1) Protects against broken / shorted switches
2) Provides priority for the pilot input
3) Allows you to use simple, low current switches like those found on most grips
4) Adjusts the speed of your trim based on airspeed so it's never too sensitive or not sensitive enough
5) Gives the Dynon Autopilot the ability to auto-trim when the AP is engaged
The VP-X trim controller does a lot of what the Dynon controller does, but it's really #5 that means you should use the Dynon controller if you have both a Dynon and a VP-X. Auto trim when using the AP is pretty awesome.

Thanks (Dynon Avionics). I love it when manufacturers comment.
I wish they would use a name. Makes me feel like I'm at a restaurant yelling "waitress". I always address people by name.
