Default Getting ready to order some wings! (slow build)

I just about have the RV10 emp kit finished up. I'm just waiting on some composite materials to arrive. In the meantime my mind has now turned to the wings. I need to get things in order before I place my order.



Vans Wing kit options-

1. Landing lights- I will probably go with the sunspot LED landing light kit that vans supplies

2. Aileron trim- Will be doing this. "operates independently from autopilot". If I want an AP system does this mean I'll need different servos for that too? At what point do I need to start thinking about an AP system?

3. Float fuel sending units- Will be going this route.


Things I'm starting to look into:

1. Wing and tail position/strobes.
2. Pitot (will probably upgrade to something heated)
3. Stall horn (is this included in the wing kit?)
4. AOA
5. Would like to do a Garmin IFR type setup /w AP, but I need to research this more. should I be looking into this now as well?

When is the right time to get some wiring/crimping tools? Now? Or are they not needed until mid-way through the wings? (I'll probably splurge on the steinair master kit).


Is that a good list? Is there anything else that I should be researching right now?

Thanks

I'd hold off on everything deferrable. The landing lights are one of those items, IMO. That technology (LED's) continues to improve at a rapid pace. Order something today and it might be obsolete by the time you're ready to fly.

Strobes are similar.

Yes, the stall warning is included in the wing kit.

On electrical tools, there is no need for them until you are buying avionics. On the other hand, there's no penalty for buying them early.

Avionics? Don't even think about 'em until you're working on the finish kit. What you look at today will be 2 generations out of date by then...

Ditto what Kyle said.

It doesn't hurt to look into the avionics now. The various companies have their operating and installation manuals on line to download. However, as Kyle suggested, they change rapidly and whatever you read now will be out of date to a certain extent, perhaps significantly, when you're ready to buy them.

Stall warning and AOA? I'd ditch the stall warning and just use the AOA. Properly set up, it will be more valuable. I don't believe Garmin G3X is going anywhere, but the screens may improve/change slightly. The Garmin A/P is prolly the best there is.
Aileron trim- My -10 was built with electric rudder trim and it is very functional. I rarely miss the ability to trim the Ailerons. The A/P takes care of that.

As others said, look now but donít buy until close to installation. You should count the number of wires you think youíll be running under the floor or thru the wing, double that number, and run them before closing up the floor or wing.
Aileron trim. This is just a motor driven spring, so yes, you need a separate servo for an autopilot. I have a good (Trio Pro) autopilot and no aileron trim. The only time I miss the lack of trim is when hand flying an instrument approach, but then I really miss it. I may install it at some point.
Stock stall horn is nearly useless with good ANR headsets, AOA is much better. BUT, most AOA systems require in flight calibration, so you may not have it for that first or second flight.
There are lots of good avionics out there. Study the options.

Going to have to disagree with Bob on this one. I have Bose A20s and can hear the stock stall horn just fine.

I agree with Kyle on deferring as much as possible until later as there's not much that benefits from installation during the wing"s construction other than condutit and perhaps the roll servo (and even that's not a big deal to install later especially if you have not decided on a brand). Items like the landing light or aileron trim are in the it doesn't matter category-- maybe slightly easier to install during wing construction but really it's a wash IMO.

OK thank you all, I will hold off on those then. Hold off on the pitot too?

The pitot tube - or at least the pitot tube mount - is easier before the skin is riveted.

Could be my LightSpeeds have better noise attenuation?
Could be my buzzer location under the panel is not optimal?
Could be my 69 year old ears aren’t what they used to be? (my wife votes for this one)

....
Having just done this work in the 1/2 built kit I purchased, I would say don't run any wires in the fuselage yet, simply install at least 4 conduits under the rear seats to accommodate future wiring. Vans pre-made bulkhead holes allow easy wiring over the wing spar.

I haven' worked on my QB wings yet, but one conduit should do the job there.

Congratulations on completing the empennage kit!

While I elected to use the QB wings kit, I believe it has little bearing on the answers to your questions. So based on my experiences to date, I offer the following comments:

As others have noted, LED lighting systems are being improved, so waiting to make final selections is advisable. If you intend to put the lights into the wing tips, (e.g. AeroSun VX landing/taxi lights and Pulsar NS nav lights - the lights I selected) there is no need to finalize these until you are ready to finish and install the wing tips. Note however that with the AeroSun VX you will need to cut into the wing tips to install an enlarged/cut-back opening to accommodate these larger lights. If you intend to place the landing lights into the leading edge of the wings, I suspect it would be easier to make these cuts before attaching the leading edge skins.

The trim servos are separate from the autopilot servos. With the Garmin G3X system, the trim servos are wired through the AP servos, so that the AP servos can adjust the trim to reduce the forces on the AP servo. I installed the AP servo mounting kit into the right wing prior to installing the bottom skin, which made the installation easier. However, I did not purchase the AP servos until I was ready to purchase all of my avionics system.

I elected to install the roll trim into the right wing (not the left wing as called out in Van's plans), and found it best to install the spring attach points to the aileron push rod before final install of the rod. The trim motor itself attaches to the back of the access plate, so it can be installed at any time.

Suggest you purchase and install the pitot mast before installing the bottom wing skin. The actual pitot purchase can wait until much later and be purchased with the rest of the avionics equipment. The standard mast should work with either the Garmin or Dynon/AFS pitot.

The Van's wings kit comes with a stall horn assembly. Your call as to the need for both a stall horn and AOA in the same plane. I elected to not install the stall horn, as I believe the AOA provides much better information regarding your approach to stall, and is included in the G3X pitot/EFIS system. If you do not install the stall horn switch, you will need to close the pre-punched holes in the left wing leading edge with a couple of rivets. Note you will need to close these holes in the right wing leading edge in any case. You should do this prior to installing the fuel tanks.

Avionics are changing rapidly right now, so I would suggest you wait to select your system until you are working on the finishing and/or FWF kit. If you purchase this equipment now, it will likely be obsolete before you are ready to install it. If you are reasonably certain you will use Garmin avionics, I would recommend you purchase and install the AP servo mounting brackets prior to closing up the fuselage top. If you decide to install the Garmin yaw damper servo, you may want to install that mounting unit before you complete the F-1035 assembly area, as doing this later requires drilling out several rivets. Not a significant time savings, but a bit of a nuisance to have to do.

No need to buy the crimping tools now. However, I would suggest you do your electrical system design and run the wires before you close up the fuselage by installing the cabin top. You may find later that you need a few more wires, so suggest you install a conduit or two and perhaps install a few spare wires. I also installed my wing wiring and pitot tubes into the wings before installing the bottom skin, and am glad that I did.

Hope all of the above makes sense to you, and is helpful. If you have questions, please feel free to ask, either through postings are via Private Message.

Enjoy the build.
