Has anyone had this issue:
From one flight to next, I seem to have issues with aileron trim. One
flight straight and level, next flight left wing heavy. Next flight not
so bad. Seems to be the model of inconsistency.
Should this be changing so much? Fuel levels, tank imbalances,
passenger loading all should have much of an effect right? Most of the
mass is near the longitudinal access of the airframe. The only thing I
can think of is that maybe the flaps in the retracted position are
sitting differently after each flight.
Any ideas?

Is it tied down outside??? Rain may be an issue.

I have had my Tiger for 29 years tied down and hangared and this has
always been the case. Seldom enough to ever require readjustment of the
trim tabs though.
Rain can affect aileron trim during flight though. Sometimes
significantly.

Larry,
I sometimes have the same issue! Coming home from E45 (Pine Mountain Lake)
last Sunday, even with heading auto-pilot, it wanted to fly left-wing low.
Other times aircraft flies perfectly level. I have fiddled with aileron trim
several times.
On another issue, anyone have any idea why one of my EGT temps is 150
degrees less that others (1145, 1300, 1310, 1280)??
Thanks
Ron Burgher

It's probably running considerably richer than the others. Try leaning the
engine significantly more and see if the don't even out more. Do it at
3000-4000 ft and 2500 rpm and you can't hurt the engine no matter what you
do with the mixture. Lean until it starts to run rough and then enrich just
barely to smooth it out and see what your temps are.

Larry,
About 14 years ago, I flew an AG5B to Florida to deliver it to a new owner
. I had picked up the plane in the Bay Area and flew it to Lancaster. It
was 'out-of-trim.' So, when I landed, I gave the aileron tab a little tw
eek. After the annual, it was out the other way, I landed, did a smaller
correction and then reflew. It seemed ok. During the flight to Florida,
I fought aileron trim issues the entire flight. I tweeked it every time
I stopped for gas. I could not get the trim set right.
At that time, I hadn't thought much about the flap rigging on the plane.
On my plane, I have the flaps reflexed enough to cause a roll change based
on flap setting. Works kind of nice to correct for fuel imbalance. I'm
not sure it would work on all planes. Try tapping the flaps down a degre
e at a time to see if you notice any change.
It is true that passengers and loading will have an effect on roll; enough
to be annoying.
