Way easier is to buy a bottle of liquid Boelube from Avery or Spruce. (4.95
I think - be sure to get liquid and not stick)
To Bill S......why .......be sure to get liquid and not stick?

Thanks, Jerry. Good explanation. I did try damping it by holding the aileron
trailing edge with my fingertips, but no success. Never has been as issue on
test flights so far, and I want to retain the precision tracking in the air,
so I will leave well-enough alone.
I do think that this incidental stick-shaker feature would get my attention if
I ever tried a takeoff with the servo engaged. Still, it's nice to have the GPS
ground roll disconnect software built-in :-)
Anticipate gain control test flights today,and will contact you if I have any issues.
Directions look very straightforward.
I will copy this to the RV list for general edification; many are following this
discussion and I want them to know how helpful you've been and how good the
EZ-Pilot is, IMO.
All the best to the tres hombres at Trio,

Subject: RE: servo oscillation
Bill, that phenomenon is caused by the very narrow "deadband" in the Navaid servo.
It is seen in some, not all, aircraft with fairly massive counterweights
in the ailerons. It also varies with how free your controls are - i.e. if you
have a little friction in the system it will probably damp on its own (not that
I recommend putting friction into your control system). It can be eliminated
or reduced by opening up the deadband area of the servo (an internal potentiometer
adjustment), but his will also affect the responsiveness of the servo
somewhat and reduce its performance characteristics. If you can tolerate the
stick shake on the ground, I would say to leave it alone and get the better performance
in the air.
What is actually happening here is common in classic servo systems that are "underdamped",
often for better response. When you turn the servo on (on the ground
where there is no airload on the ailerons) the servo will move the ailerons
to the neutral position. Because of the mass in the ailerons and the rapid
movement of the servo it will reach the neutral point but the mass will cause
it to overshoot a small amount. This will generate an error signal causing the
servo to rapidly correct in the opposite direction (again with a small amount
of overshoot). As this process repeats, you get the oscillation that you mention.
The narrow deadband does give the servo the ability to react quickly (as in turbulence)
and to input very small corrections to the controls for extremely fine
tracking control.
We can give you directions on how to reduce or eliminate the effect if you want.
However, as mentioned, It may reduce the performance some in the air. Because
there is no need to turn the servo on while on the ground, except for the
preflight check, you shouldn't find it to be a big problem in normal operation.
It will definately not harm the autopilot system in any way.
If you'd like more information, please let us know.

Subject: servo oscillation
Do I need to do anything about a 2-3 Hz joystick oscillation that does not damp,
caused by activating the aileron servo while the airplane is on the ground not
in motion?
Thanks, guys,

September 2 is approaching, gang.
I have the following couples on my short list of participants:
Millsaps
Leggettes
Barbees
Williams
Bowens
Boyds
Glasgows
That's 14 of us. There's room on the island for more :-)
I'd like for everyone who's still "in" to confirm here on the list. Anyone dropping
out, please tell us so we can give your room reservation to someone else
in the group. Those of you who didn't get a room at the Crews Inn, where are
you staying? I suggest we carry some of those PRS walkie-talkies (the kind with
the 14 channels and the 38 privacy codes) so we can coordinate group activities
like dinners, sightseeing flights, etc. That might be especially helpful
for those in our group who are lodging elsewhere.
I made a few calls today and found one place that will not only reserve rental
bikes for us, they'll drop them at the airstrip for us and let us leave them there
when we depart Monday. The rental rate is $23 plus tax for a three-day adult
bike rental, ($39 for 3 days for a bicycle-for-two tandem rental). They
want a credit card prepayment, and will then give you the combination to the lock,
so you can ride away from the tie-down area in style on Friday. For those
who may not know, the island is small and everything is within walking distance
of a fit person if you've got all day, but bikes are the way to go! The Crews
Inn lodge-keeper has been generous in the past with automobile pickups and
occasional rides, but for the most part we'll need our own transportation while
there. Bring safety gear like helmets, lights/cyalume sticks for night riding,
and bug spray. I warned you ;-) IMO, Backpacks are a must for getting
gear and purchases to and from the beaches and shops
on a bike, but I htink they have handlebar baskets, too. To reserve your two-wheeled
transportation, call Beach Outfitters at 252-928-6261. Might want to
mention that you're with the group of pilots staying at the Crews Inn Sept. 2-5.
I did not ask about their cancellation/refund policy, but keep that in mind
if your plans are in doubt. There are other places to rent bikes if these guys
run short, but the other places won't reserve them or deliver them.
This is going to be fun! Let's hear some ideas for things to do while we're vegging
for three nights on the Outer Banks. I'm bringing my laptop, humidor, and
some "spam can ham radio" stuff to amuse myself if y'all get too boring. Folding
beach chairs & umbrella. There might be room left for my guitar if no
one pays me enough to leave it at home.
Sound off! Roll call!

The stick just doesn't,.... stick! One drop of the liquid and it's done.
Liquid also works better for drill lube.
