we got 5th place cornell and we didn't use a flaring prop

Flaring props will give better times in lower ceilings.

When I built the kit I followed all the instructions on wing setup. I had left wing wash in on the main wing. Over time the wing has "warped" and now needs modification. On the main wing, both trailing edges are lower than the leading edges at the ends of the wing. I've messed around with the support struts but that doesn't do it. Is there a technique to "Re-warp" a wing? Could I slightly dampen the balsa, attach it to a form, and let it dry? Will that work or will it damage my wing?

The plane is still flying well except during the initial high torque take off. It wants to fly straight for a long way and then it starts to circle. It didn't do this before so I'm thinking it has to do with the wing changing shape a bit. Any ideas would be great.

Have you tried acetoning the strut, adding a warp to the wing, and re-gluing (would have to be very careful not to undo any mylar or ribs however)?

Yes, I tried resetting the struts but it doesn't have a big enough effect on the end of the wing to eliminate the wash in on the right side of the wing.

so ur issue is that its not turning at initial start
meaning do you want a smaller circle?

Better circle at the start. Yes. Once it gets going it circles fine. If we launch with .3lbs/in or more it flies straight for 30 - 40 ft before turning.

maybe just tilting the stab more or adding another turn factor will help

How much offset do you have (out of curiosity)?

When you say offset do you mean shifting of the wing to the left of the plane? If so, both wing and stab are about 1/8" to the left...about 2 rib widths.
