Default Aileron Rigging

Has anyone rigged their ailerons yet? If so, how many degrees of travel do you get up and down? I'm particularly interested in Down travel. Measured Van's 14 at OSH and it was 25 degrees. I'm getting only getting 18 degrees?

Are you sure you measured Vans' with the proper reference?
25 sounds like too much down travel. 15 is typical aileron down travel in most aircraft. 25-30 sounds about right for up travel.

Default Aileron rigging

Mel,
One of Vans guys measured it with his I-phone so I can't account for the accuracy.
The point is, at 18 degrees my aileron pushrod rubs into the inboard aileron bracket and stops. Vans pushrod doesn't even come close to rubbing. I've been over this thing and the plans six times trying to find something put together wrong and I can't. Everything is prepunched, so I'm wondering if this might be a design problem and other people are affected?

Default torque tube rubbing

Mine rubs as well. The advice I received was wait until the wings are installed and the rigging is complete. It will not rub then.

Default Aileron Rigging

The ailerons on Vans 14 travel further down than mine and the pushrod doesn't even come close to rubbing on the inboard aileron bracket?

Default aileron

I would think you would want the travel to be according the plans. I would not use some guys iPhone inclinometer as a reference for rigging.

I'm final rigging my ailerons now and thought I had the travel limits to check my work but I don't see them in the finish kit instructions or the wing instructions either.

My take when building was this, until the wings are on the plane and rigged to the sticks, you can't measure down travel.

With wings on the bench, all you can do is set neutral and possibly check up travel. The up travel stops dictate down travel of the opposite aileron.

I haven't been worried about the push rod tube making contact. Mine does, but by my estimation the down travel is more than enough and the stops will in fact stop it at the correct location before the tube makes contact.

Seems ok to me.

Ron,

Do your aileron push tubes rub before the stops are hit?

My fuselage is not finished so all I have done is rig per the wing plans to set neutral.
