Capstan Travel?

[Mark P.]

To connect a servo to my elevator cable, I need just under 5" of travel. Right now my servo has the standard arm on it with a max travel of 2.6".

If I change to the capstan, does that allow for more travel?

What servo are you using? The C (capstan) servos I've seen for cables don't have arms. They have a rotating drum the cable goes around.

 

[Mark P.]

AH! It looks like the capstan servo is an entirely different servo. I thought the process was to take off the arm on a regular servo and then add the rotating drum. I now see that on the Dynon website, they list the capstan servo as a whole separate servo. Looks like a call to Dynon is in order!

They might be the same except for the drum/arm. I don't know. If so, ask if you can buy a drum separately. That should be a lot cheaper than a whole new servo.

Dynon will swap out servos if after you get one installed it turns out need one with a higher torque range. They might do a swap of one with an arm for one with a capstan too. I think the price is the same for arm or capstan.

Yes, they're all $750.
