I was warned when I started, to maintain high standards but not to get hung up on achieving absolute perfection....guess itís about finding the balance but a safe one at that
My rudder had a bit of a twist. Like you I sent photos to Vans and they said not to worry. It turned out to be a non-issue. So the advice to "build on" is good advice!
Now for my suggestion! Fly your plane with that "9" rudder for six months.
Then build an "8" rudder and install it. You'll have to change the vertical stabilizer top faring too, so be sure to put -6 nut plates up there.
Be sure to weigh the rudders and adjust your W/B.
You'll be so happy with the difference!
I did this after about 2 years of flying the 9 rudder.
I think it makes the airplane look better too!
As you may know the very first 7's came with the 8 rudder. But Vans didn't like the spin recovery of the 8 rudder. I've heard it was like 1/2 a turn too long. Somebody please correct me if that is not correct. So they decided to use the 9 rudder and it came out of a spin with less turns.
So in the end that rudder you are concerned about now should eventually wind up on the wall of your man cave, IMHO
