Default Rv 10 aileron trim spring noise

Hi everyone !
I hate that noise when you move the aileron or the stick in ground.

Did anyone solve this ? Or maybe I have a construction issue ?
Thanks folks !

Default ALSO...

If you are using a garmin system, it has auto trim capability.

This requires that the servo drive wires are connected to the roll servo (2 wires).

The default location for the aileron trim is in the LEFT wing but the roll servo is in the right.

If you mount the aileron trim in the RIGHT wing, it simplifies running the wires to the roll servo for the auto trim function.

Mounting the aileron trim in the LEFT wing and using auto trim, you will need to run those wires from the LEFT wing trim servo to the RIGHT wing roll servo.

Just something to consider...

The only way I know to install it, after the wing is attached, is to take the wing back off. You have to put two attachment points for the springs on the Push Tube, which means pulling the Push Tube.
In short, make up your mind before you attach the wing.

You do not have to remove the wings. Disconnect the both ends of the push road, remove the wing tip fairing and slide the rod out the end of the wing. A lot less work and time involved

Default URGENT :NO NOISE PLEASE

"Hi everyone !

I have now found 3 x RV-10's that have had the Aileron Trim springs rubbing on the Aileron pushrod tubes. The plans were changed to require the builder to inspect and confirm that there is no contact in 2016, however prior to that I guess builders just kept building.

The fix is simply to bend the Aileron Trim Motor arm ,forward, away from the Aileron pushrod approx 3/16".

If you have any noise, please inspect, as the springs will eventually wear through the pushrod with possible dire control issues !!

I've seen the same on another RV-10 before, as well. They replaced the pushrods. Definitely inspect and listen for any scraping.

Default Rv10 aileron trim

Guys,

I never liked the Rv10 aileron spring trim, so I took mine out and off completely. The plans trim system did not appear to be effective to me on my 10 in the air and additionally I didn't like the spring applying pressure to the stick or my leg after landing and taxiing. I purchased the 1" servo drive from Ray Allen, removed my left aileron, installed servo, attached trailing hinged trim tab (about 7" piano hinge) with horn/push rod to the Ray Allen motor installed in aileron. I love it.

I don't know how to post pictures, but I can send pictures if anyone would like to see a few. Send me a PM with your "regular" email address.

Rob, if you want more details the installation instructions are on the thumb drive from Vans - OP-38. The springs connect to the aileron control tube 6" inboard and 6" outboard from the trim servo arm.

As a "belt & suspenders" option, I put some UHMW tape along the push-rod tube to provide some rub protection just in case the spring were to contact the tube.

Bob, in process of wiring roll A/P and trim motors now. Can you direct me to Garmin information regarding which 2 wires to run over to right wing and how to tie them in? I already have trim motor in left wing, so will need to run the 2 wires over to right wing.
