Now there's something ironic. I have been working on my 4*60 (the tank plug shrunk over the winter) and turned on the plane to check the neutral settings for my elevator and rudder. Both were way off center and I had to correct. I used the nylon rods on this plane (mostly because I didn't know any better) and both control surfaces were off to the direction that would indicate shrinkage in the rods. The cold wx we have been having must have been the culprit, and here I couldn't figure out why my programming had changed so much. Now I know.
