Trio uses a clutch in their servos - but I don't think it is compatible with a TruTrak driver.
Per Trio literature
, It's a slip clutch. Which means if you really crank on the stick, it will allow the control to slip past the servo input.
What I'm asking is a clutch that only engages when the AP is on, so if it's not on, the control has no servo motor/gear resistance.
I've had mine apart and played with it. I can assure you that when off the clutch physically disengages, and the external arm is very easy to turn. The 'slip' part is fail-safe #1; if for some reason it won't disengage, you can overpower it. (Fail-safe #2 is a nylon gear that will strip with sufficient applied force.)
As you can tell, I'm very happy with the Trio. Flies approaches a whole lot better than I do!
Nice! Can they be found used?

The servo for the Navaid Devices wing leveller is similar, and you may find a used one if you look hard enough. If you do find a Navaid servo, it is compatible with the Trio control head.
I flew behind the GSA 28 and now I can't go back to an un-clutched servo.
Have there been any attempts to build something like a clutch or anything like it?
The idea is that if the AP isn't engaged, it just slides with almost no friction.
Just wonder...
If you can tell the difference in flight between a modern stepper motor servo with no clutch and the GSA 28 as it relates to feedback on the controls when disengaged, you have some super senses
I have trutrak servos and they are not detectable when hand flying. But then, maybe there are some that can feel a pea under a pile of blankets......
