I had not realized how much you have to pull on the springs to set them in place. It would be a lot easier with wings on a bench or in a wing stand.

This is very helpful - I have QB wings on the way.

I think I'm at about 165 hours on the -14 now. I have Aileron trim and use it quite a bit. Inevitably whichever seat I'm in, which changes from day to day, requires the pilot to trim to the opposite side, and it's made worse if the fuel loading is higher on my side. Yes, if all you do is fly around your locale, and you most often fly alone, you probably won't miss it, but, if you fly long x/c trips, or switch seats, or add/remove chubby co-pilots, you will definitely find you will occasionally use it. In looking at my panel indicator, I often see the trim cranked within 1 bar of either side limit, so I know it's definitely getting used.

I don't have a Yaw Damper but to be honest, don't know what I'm missing. There are times it may be nice to see, but I've never flown an RV with one, so for now, ignorance is bliss.

Correct me if I am wrong but wouldn't setting the aileron push rod to the neutral position involves attaching the push rod to the stick so the stick is also at the neutral/vertical position? How can that be done with the wings not attached. This is of course unless the basic measurements that Vans gives is used as a guide.

There is a jig that holds the aileron bellcrank at the proper angle for neutral. Adjust the pushrod so the angle is set there and also at the wing root. Now the wing is completed as far as that pushrod being properly adjusted and you can then remove and install the aileron trim setup. The control column stick is a separate adjustment made later.

What Chris said,

The jig is easy to use and all the wing rigging can be accomplished off the plane. When I attached my wing, I just confirmed the aileron was positioned correctly after attaching the wing, and then did the stick adjustment.

No changes were made to the aileron push rods while on the plane. They worked perfectly as set off the plane.

Thank you Bob and Chris for chiming in. I did have a jig for my RV7 to set the aileron neutral position but when you attach it to the stick, there are other [fine] adjustments that need to be done on the pushrod so your stick is also in the correct position.

I am still ways to get there but the more I learn the more prepared I will be.
