FireFlyers,
I made some new aileron yoke control arms to improve roll response. How it
was done can be seen at:

I recognized there was a little play in the system at the "Tee" bar, but I
did not believe it caused enough of a problem to be worth the effort to
change it. But, after moving to I22 with a different runway orientation, I
discovered that most of my flights start and stop with a cross wind. Also,
the average wind speed seems to be greater here than what I experienced in
Missouri at K02.
With a little bit of play in the stick, you lose the hand pressure sensation
as the ailerons rock from one side to the other. While this is happening,
the FireFly tends to get a little ahead of you because you have to move
through the control dead space to keep the FireFly side slipping down the
runway center line. As result you keep hunting and wobbling from side to
side of the center line. Removal of the play removes all stick displacement
and all one has to do is add or reduce pressure to keep the FireFly side
slipping right on down the center line.
