Hi all
Question for those who have installed Vans electric aileron trim, is there any reason the servo can not go in the right wing instead of the left?
Thx, Rick

You will have to mirror image the plans........
I don't know of any reason, other than roll servo is usually installed
in right wing, which shouldn't make much difference.
Not visualizing what advantage either wing would have, but have decided
to defer getting aileron trim until have flown for awhile to decide if
the perceived benefit merits the cost and labor.

Speaking of which, does anybody have a digital copy of the aileron trim installation drawings? I am needing to make some adjustments on one of them and need to know how it is installed.

Just my 2c, i use aileron trim on every flight and consider it
standard equipment. Otherwise, you will have to constantly apply aileron
force (when not on autopilot) to fly wings level as weight varies side
to side.

Depending on how often you fly alone and how far, I have used my trim, but
the truth is I don’t see a real benefit to it. I use the fuel on the left
side first and that usually balances out the plane for me, I have a tab on
the rudder, works fine for me. No regrets with not adding a electric rudder
trim. My point, You're are right on Kelly. Wait and see if you need it, just
as I did with the rudder trim.

That is why I am waiting. I have flown my Mooney for 14 years with
similar wing tanks, similar loads with all sorts of fuel imbalance with
same pushrod type controls and didn't feel any need for aileron trim.
Recognize RV-10 maybe different, with shorter wings, but since it can be
installed later, I will wait and see.
Usually mods that we have spent money on turn out to be the best, and
the rest...who knows.

I use mine about every other flight. I would install again if starting
over.
You getting close Kelly? Maybe I'll run down there and see your project
this winter when it's cold in SLC.

I use my aileron trim on a regular basis and would definitely do it again if I was building another -10. This airplane is more sensitive to lateral imbalance than any other light plane I have flown. I definitely would not install rudder trim if I was building again. I rarely use it.

Wow! That is the exact opposite for my plane. I don't use the aileron trim but need rudder trim all the time....

I use both rudder and aileron trim when hand flying and rudder trim when on
AP. If I was building another 10 I would definitely put both in. The
aileron trim is much more important when solo.....

I use my aileron trim every time I fly. I can't believe how sensitive this airframe is to fuel imbalance and passenger load. I like the option of having my Aerosport rudder trim, but I set it a while back and it hasn't moved in a while.

Hi Kelly.
Just to put a finer point on it from someone who has just a little time
in a Mooney and 200+ in the '10. The difference is in the relative
'stiffness' of the aileron control.
As I recall, the Mooney has enough system stiffness that it tends to
blank out small roll trim requirements. It's mainly a matter of
managing the tanks to keep the trim close. The wings tend to stay where
you put them which is a very nice thing.
The RV10's control system is tight and light, but not stiff at all. A
small imbalance is easy to overcome but will require constant pressure
and/or attention. No big deal but no hands off at all if out of trim a
little bit.
All this applies to hand flying only. I find myself doing very little
hand flying these days except for airport ops. And frankly, I rarely
touch the roll trim if I'm actively maneuvering the plane. It's not
really needed in that context. It's just hand flying while smooth air
cruising where trim is desired. So if you cruise with the AP and manage
the tanks properly, you really won't miss the roll trim at all.
There may be a difference between yoke flying versus the stick. My old
Maule was always out of roll trim but without an AP, my hand was always
on the yoke and it was easy to hold in the required roll trim. I find
the stick less comfortable in the same situation. I actually miss my
old yoke (shields up!)
Good Luck

Does anyone out there still believe in the KISS principal? Like Bill, most of my distance flying is by autopilot, and if you monitor the tanks properly, it's really a non-issue. Haven't found the need for either rudder or aileron trim. Less weight, less $, less work, and maybe most important, less that can go wrong.
My 1 cents worth.

All good points.I'm one of those who believes in trim, trim, trim. Trimmed hands off is the most efficient your airplane will fly. It is also the 'state' your airplane should be in when the auto pilot is engaged. Even flying the MD-11 I trimmed to hands off before engaging the A/P and would occasionally click off the A/P enroute just to insure the control pressures were neutral. Finally, trim can be a backup flight control system. Years ago I instructed in T-34Bs (1,000+ hrs). One demo I gave was a complete circuit in the landing pattern using only trim. Trim is your friend!
Cheers,
Jim

Funny you should mention the complete circuit using trim. Years ago when trying to learn to land a C150 at age 16, the instructor flew the pattern with trim-only. Pitch trim that is, and rudder and power of course. It showed me how unnnecessary my death grip on the yoke was.
Anyway, does that mean that the MD-11 A/P didn't operate the trim when engaged? Or was it just a good habit that shouldn't be broken?

Hi Bill,
The pitch trim on the 'Dog' is very good and works on the A/P. Roll and yaw trim are manual. The system trims by taking out control pressure to within a certain value. This will allow 'some' amount of control pressure to build up before the actuator moves to neutralize the elevator control pressure. One can engage the autopilot when not 'in trim' and the system will trim for you. If the elevator is too far out of neutral pressure the A/P would not engage. The A/P will also disengage if an excessive control pressure can not be trimmed out and the accumulated pressure exceeds a certain value.
Another factor that needs to be considered is what happens if the A/P fails or the A/P is simply disengaged when an out of trim condition is present. Generally an abrupt control input is the result. This is undesirable, particularly at Mins.
I'm new to small airplane autopilots and their capabilities, but I'm eager to learn. The avionics for the homebuilt industry is amazing. That being said, it seems that using the aileron control servos to "trim" for you will cause an unbalanced flight condition. . . maybe a yaw damper would help. Unbalanced flight is less efficient, hence more fuel burn.
I think it is a good habit to always be in trim. I've been fortunate to be flying for fifty years and believe in stacking the deck in my favor when I can.
Final caution, "George", the A/P, is a great tool, but don't let him become a crutch.
Cheers,
Jim
