Default RE: Correcting incidence

The information present here is appreciated and has been extremely valuable. However as a long time flyer but a poor builder correcting an incidence issue is a daunting task. Like other things the learning process is laced with danger.

1. Make the wing saddle first. I didn't.
2. Try not to loose your reference points. I lost mine.
3. I attempted to sand the saddle after each change. After a couple of days decided the approach was backwards.
4. After checking incidence and turning everything upside down right becomes left and left becomes right. I knew that but somehow forgot many times anyway. Always discovered after 30 minutes of sanding.
5. Disconnect the servo from the ailerons first and clamp ailerons in a centered position. I didn't.
6. Somehow attach the leveling shims together and to the table so he airplane will stay in place while being checked. I didn't and still look for more shims every time a wheel jumps off of a leveling stack of shims.
7. Use a single short shim (less than one inch) and check incidence. I didn't. But I am now.
8. Don't forget that a long move requires moving the dowel holes. I didn't move the holes far eought.
9. Don't forget that on a long move the nylon bolts at the rear of the wing will not screw in straight like they were in the beginning. I forgot.

This has been a good experience. A good builder would not have the problems listed above.

The forward plan is:
1. Shim
2. Check
3. Shim
4. Check
5. When close fly to see if I went the correct direction.
6. If wrong direction the airplane will break an I am done.
