If you want a connector in the wing root we happily add it for the cost of the parts (about $10) in addition to the main harness. I personally try to discourage extra connectors in the wing root on most RV's, but many people do put connections there and we are happy to do it.

to allow wing removal
 
Stein,

I guess I don't understand. If you don't recommend terminating the wiring runs through the wing at the root, where do you terminate them?

Terminate things either at the loaction of the item in the wing or terminate it at the panel. Either way, simply coil up the excess wire either in the butt rib or in the fuselage, and when inserting the wing the final time run the rest of the wires through the fuselage and up to the panel. For example, you can have all the light wires, etc.. run to the root of the wing, then leave 8-12' of extra wire coiled up in the rib. When the wing is put on for the last time, uncoil the wires and run them up to the panel. You can leave yourself a service loop or bend down in the wing root if you are concerned about removing the wings int he future. Normally you won't have a need to remove the wing later on in life unless it's bent or broke (or possibly removing it for export).

Cheers,
Stein

do you have instructions
 
Stein,

do you guys have detailed instructions on what I need to install now during my wing contruction? i intend to buy the AP from you guys but in stages. So some builders suggested the mounting brackets for now. I guess if i have some detailed installation description, i can make a proper decision.

Thank you.

I can only speak for Dynon, ACS has the servo mounting bracket kits available for order. They are $75/ea for pitch and for roll. They are all inclusive with detailed instructions.

I'm sorry but we do not have a detailed list of instructions because there would be many variables. Here's what you "could" need to install now. It's certainly not a complete list, but some of the items you may need:

1) Servo mounting brackets.
2) Roll Servo (easier to do now than with the wing on the plane).
3) Wire for servo
4) Pitot tube mounting bracket.
5) Pitot tube wiring if using heated pitot
6) Pitot tube plumbing for Dynon AOA Pitot
7) Regular pitot tubing for other pitot tubes
8) Strobe light wires
9) Strobe light power pack if using some brands.
10) Nav light wiring
11) Landing light wiring
12) Taxi light wiring
13) NAV antenna (or possibly comm, but I wouldn't recommend it) for the wingtip.
14) MKR antenna
15) Coax cable for said antenna above.
16) OAT probe if mounted in the wing
17) If using an old style aileron trim servo, run wires for it.

That's about all I can think of off the top of my head. You can mix/match the above to end up with your configuration.

Cheers,
Stein

Looking at your list here, is it true that I can run all the wires together through my conduit, Except the "NAV antenna" and "MKR Antenna" which would be 2 coaxial cables, to not get noise interference.

The SteinAir harness -- at least for the TruTrack, comes with D-sub pins attached at one end but no connector. The connector is already installed on the other end (the controller end, if memory serves, which it frequently doesn't). So when you're ready to run wire, you can get them through .

I drilled holes and ran conduit when I made the wings, but I didn't run any wires until about a year ago, after the wings were already attached. It was a non issue. I simply cut the conduit at the access hole, ran the wires down the rib (adding two Adel clamps) and ran the rest of the wires -- nav/strobes -- out to the end of the wing.

I installed the TruTrak servo during wing construction, but it's pretty easy to add it after a wing is finished, too.

You should have no worries here.

Yeah, what all these guys said. I put a TruTrak in the right wing. Instructions were detailed and taylored for an RV. The package included brackets. I believe if you go to the TruTrak site, you can download the install manual. This will give you a heads up as to what is needed. Don't know about Dynon.

I ran all the wires in the plastic conduit and the nav coax through a separate routing hole protected with plastic push-in grommets reachable through the inspection plates.

To route all the wires I first tied a cotton ball to a piece of long string and shoved the ball into the conduit. Then get the vacuum cleaner and from the opposite end of the conduit suck the ball with the string attached through the full length of the conduit. Now, just tie your wire bundle to the string and pull it through. I left a spare string in the conduit "just in case". I also left another string in place from mid-wing where the servo will sit through to the root rib.

I used a 9 pin sub D connector at the fuselage/wing mating area. Stein has the connector, pins and crimpers. Hindsight, instead of the connector, I would put in a service loop and just hard wire it. Hopefully, I will not have to remove the wings.

How much wire do you guys leave hanging out of the wing to make it to the instrument panel. Also so I can calculate needed wire size for amps.
