OK, you state 3" from center the left wing incidence is at +2 degrees but as you move away from center it tapers back to +1 degree. That shouldn't be a problem and you should be able to trim it off with aileron throw. Here's what I'd do....

Fly it like it is, being conscious of the incidence factor. Does it want to roll left at neutral aileron? If so, find the ‘happy’ medium, land and check the amount of throw on the left wing. Now, remove your clevis, turn in until the radio is back to neutral and re-attach. This should help to counter the incidence of +2 degrees.

Fly again, trimming accordingly.

Who knows, the aforementioned problem might not cause you any headaches!!!

Thoughts gang?
