Denny Dart II Wing Twist

I made careful measurements of the angles on my two Denny Dart IIs. The wing incidence was too much on the one with the shim. I took 1/32″ off the shim. I also got the wing straightened out. I took it out for a quick test in front of the house. It was a very hot, dry day today. It was twisted again before I got it off the porch. Once in the sun, it twisted even more. Here it is:

I put in 200 turns just to see what would happen.  Fast roll hard right straight into the ground.
