I have heard that aileron stick forces can be high in the 601XL especially while coming out of left turns. I have been told that you can duplicate the trim tab that is installed on the left aileron and install it on the right aileron as a servo boost tab to reduce the aileron stick force needed. Has anyone else had high aileron stick forces? Does anyone have any suggestions about an aileron servo boost tab?

Thanks,

Scott

Hi Scott,



I only have a little time in two different Zodiac XLs, so I might not 

really understand the situation.  That said, I think there is a 

misunderstanding here about stick forces.  The XL is very responsive 

to force applied to the stick in roll performance.  The thing that 

bothers some people, particularly aviation magazine article writers, 

is the stick doesn't move much in response to the force applied - 

just the whole airplane moves.



This could be described as a lack of control harmony.  In my opinion, 

control harmony is lacking in most airplane designs and doesn't 

really play any role either positive or negative in the airplane's 

actual performance.  It is just a pilot "Feel" thing that is normally 

forgotten after a few hours flying any particular design.  For 

example, The Cessna-182 is incredibly heavy in pitch control and yet 

this is the second most popular plane in the history of aviation.



I think the idea of adding "Power" to the aileron controls would be 

dangerous in this plane.  If you really want to adjust the control 

harmony, I think the way to do it would be to reduce the size of the 

ailerons.  Just to be clear, I do not recommend doing this.

We have 270 hours on our 601XL.  I agree  completely with Paul.  The airplane really flies just fine -- don't mess  with it!  Every airplane is different and, as Paul says, you'll quickly  adjust to this one.  I'd say 15 minutes ought to be enough.
