DIY 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 didn't type that as well as I could have... TruTrak is always driving the gears, even off. And that's not cool to me. That's all I was trying to say. The GSA 28 has a clutch and when it's off... feels just like an RV should.

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......

Ever flown a RV-3 Yes, I'm that prince and the pea.

I like the idea a lot and was planning to do this also, but was waiting to get in the air first. I hope you move ahead with it and good luck.

The Trio was a copy of the Navaid servo and you should be able to find those inexpensively. However, Trio made some mods to better support the pitch axis and they only support their servo for the pitch axis.

I agree. I have the Dynon servos (similar to TT) and while I can notice the servo if I think about it in the hanger, I cannot notice it in the air. Completely smooth. If you have the bias springs for ail trim, it has WAY less impact than that.

If you like the GSA 28 servos, why not just buy those? It looks like you can drive them with a G5. G5 ($1199) + 2xGSA 28 ($1500) + install kits ($150?) = $2849. Then sell your TruTrak gear...

Edit: You might need a GMC 305/307... not sure if that's really required with the G5....
