Squeezing the aileron, or Kutta Rules!

In the post "The first hundred days. Part II", see below, or click here, I indicated I had a heavy left wing and planned to squeeze the RH aileron to fix it. I knew the theory, but was very concerned as to just how much adjustment would be required since I had never actually done it in practice.

It has taken a long time to pluck up courage to do it, but as a first step I decided to very gently squeeze two bays of the aileron with my hand seemer as you see here. I protected the paint with some old soft hardboard, and squeezed it very gently so I could just see some change in the reflection when I took the pressure off.

I was quite sure that I had not done enough but decided to add another bay each time I landed until the problem was fixed. So, today I flew, and with this gentlest of adjustment it is perfect. So, if you have to do this, go gently!

  1. Thanks for this posting Steve and also the VAF reply. I'll re-check the 9A when we pick it up hopefully this week weather permitting. If it needs some tweaking after checking rigging will certainly look at this approach.
