Subject: pinching the aileron trainling edge.
From: thomas sargent <sarg314(at)gmail.com (sarg314(at)gmail.com)>
The time has come for me to squeeze the right aileron trailing edge to try
to correct a heavy left wing. Can some one give me an idea of how much to
squeeze? I gather it is a really small change that is required.
How do you do it? With fingers? It seemed to me that a couple strips of wood
a few inches long squeezed with the fingers will do. Iplan to do about 1/3
of the length of the aileron on the first try.

Hey Tom:
1st in the 'get rid of the heavy wing' process is to get the ball centered. Use whatever rudder tab is required, then proceed to the aileron squeezing fun. Wood strips about 6-8" long will work with regular seaming pliers -- make the wood strips from paint mixing sticks. If you go too far, you can bump the radius larger with a section of 2x4.
Now, you have to remember that this sort of aileron adjustment STARTS with the aileron skin (top & bottom) completely flat. So, make sure the TE is properly squeezed to allow for flat skins before you start this process. Check the skins with your 6" SS ruler between the skin stiffeners 1st, and make proper adjustments as required.
Carry on!
