REFLECTOR: Aileron Rigging

[Tom Martino]

I had a similar problem (although I do not have a "5").  My cables were
clamped on both ends ... but flex in the line caused extra movement when
under pressure.  If you hold each aileron and move the stick you can see
where the "flex" is and correct it by securing the cable.  This may not
be your problem ... but it is worth a try.  Another possibility is the
geometry of the "Stick to Aileron Torque Tube" attach points.  The stick
attached to the right side of the torque tube.  I have found that this
makes movement to the right easier than movement to the left.  If you
look at the installation, you'll see what I mean.  This slight
mechanical advantage can cause a heavy right wing.  That can be overcome
with tighter rigging on the opposite side and/or wing washers.

 

It took me a while to work these things out ... but now my plane flies
"hands off" straight and level for miles and miles.

I would say then it's the former.  Centered on the ground, and centered
in the air, but both not in trail.

 

If the cable is clamped at both ends, what additional clamping and
where, will fix the flex problem?  Keep in mind that this is a -5 with
the drop down keel, so we have another bellcrank in the middle of the
aileron torque tube.  We don't have any freeplay in the stick but if one
guy hold one aileron and another moves the other you can get some play.

 

Thanks for the help.

When flying and wings are leveled ... is the stick centered?

 

If centered on the ground with ailerons matching ... and centered in the
air with one aileron higher ... there may be excessive slack in the
routing of the aileron cable causing it to flex under pressure giving
one side extra length.

 

If not centered in the air ... it is simply a matter of a heavy wing.

 

Washers at the upper or lower attached points can trim out any
"heaviness" and level wings.  In your case, you'd want to trim your
right (heavy) wing up and/or your left wind down.

John and I want some opinions on our aileron rigging.  We have a "heavy"
right wing.  When we keep the aircraft level both ailerons are 3/16" up
from "in-trail".  The right wing is up more.  But on the ground they
adjust to in-trail with the stick centered.  Any suggestions?
