Umm,
although it sounds like you answered your question Tim here are some
guidelines to rigging.
Set the stick to neutral by having the aircraft in the leveled condition,
and use an analog or digital level to get it straight up on roll axis and,
if I remember right, five degrees top forward in the pitch axis for
RV-6s(look it up or invent it for your aircraft).
Lock it in place.
Put the controls in the neutral condition and lock in place.
Put any bell cranks, including the trio servo, in the neutral condition and
lock in place.
Then adjust all push rods, cables etc. to correctly fit.
If the plane then doesn't fly in level it means the fixed surfaces are not
correct, or that there is a force upsetting the neutral condition of the
control surfaces as in the trailing edge issue with the ailerons or an
unbalanced fuel load causing the ailerons to need to be something other than
neutral to stay level.
But that all said it matters not to your question. If your trio ez pilot
display head is attached anywhere close to square to the aircraft along the
roll axis (level in the panel) it won't care where neutral is. It will just
move the ailerons to where the plane stops turning. As well, if you are
skidding (ball not centered) this will put the plane at an angle to counter
the turning being caused by yaw which is also known as the auto-slip feature
for those few of us with in-cockpit adjustable rudder trim.
However there is a place in the setup to tell it where neutral is by
adjusting it electronically until the ailerons are in the location you
happen to know as causing level flight. (For me this happens to be when the
ailerons are equal with the flaps and wing tips and the fuel load is equal,
and this should be true for most aircraft, at least those that have flaps,
wing tips, ailerons and fuel)
But, from what a little birdie told me the other day, you'ld be amazed at
how many never actually adjust this centered value because the unit works
fine without it being adjusted. I went and set mine to something other than
the default center of 7500 just in case that birdie ever checks to see if I
properly calibrated the unit prior to test flying. (This of course also
takes into account the belief that I wouldn't be believed if I were to say
that my plane is built so hot damn accurately, therefore I don't need no
stinking calibration.)

Hi Wheeler,
Thanks for the comments. I found in the Trio manual where I could adjust it
on the ground and then fine tune it in flight. That would be most
beneficial. Part of my problem is I do still have a heavy left wing and
according to Van's I should not fix it until after I have had somebody in
the right seat. I have yet to fly off my 40 hours and so can't do that yet.
I would be reluctant to squeeze my aileron until I have added weight in the
right seat with equal fuel. I ferried my plane from Oregon to Texas and
would have really enjoyed having the auto pilot working.
I was trying to think ahead on this deal and out thought myself I think. I
couldn't wrap my mind around how I was going to duplicate the stick position
once on the ground, but didn't realize (or remember) that I could fine
adjust within the setup of the Trio.
Thanks again for the input, appreciated
Tim
