RE: Debonair
Hang in there. Look over your plane and make sure it is to the plan. If built to the plan and balanced to the plan, it should fly great. Drilling the holes in it should not change the way you check the center of gravity. It will change the distance recommended in the drawings though. Just make sure it balances on the spar where the prints show. The 4mil on the bottom and 2 mil on the top is a great wing. Good luck and keep trying. I have built several spads and they have all flown great.
