Hello Guys:

What you need to do is find 2 spars that are warped about the same. You put them with the warps opposite each other. This is the accepted procedure, BUT. I would warn you. Check the grain on the ends of the spars. You want the grain to go as close to verticle as you can. This yields the strongest wing. If you cannot match them up. Get on the horn to Great Planes (or Tower if you bought it there) and explain that you cannot match up the warps. They should send new spars. Both have a reputation for good service. As I recall the wing has small turbulator spars in the front. If these are the spars that are warped. I would see how much. If they are only warped a little I probably would use them. The kit I built had some warp in these and did not effect the wing in any way. However the main spars are different. As I said before thy matching spars or replace them. The main spars will have a significant effect on the wing.
I hope I did not confuse you. I tend to be long winded and repeat myself. Too much exhaust fumes in the shop I fear.
