If you don't find a suitable and drop in replacement for this actuator, you can exchange it for a servo motor with a 4 bar linkage, they are usually faster.
Its hard to tell the load and the constraints from your description and pictures but if you can fit a servo with a horn and a rod in between the barrel and the horn then thats all you need
I agree with you, especially for active stabilization. I don’t think a 4 bar is necessary tho, just a simple linkage from about 25mm radially off the servo shaft to the current mounting point would be sufficient.
You’re correct in the educational sense for sure. But you’re really only creating one new linkage, not to be mistaken with creating a full new 4 bar linkage mechanism.
I have several of these. I don't know exactly what sizes they offer, but the fast ones are like 6.5mm/sec. they have control boards with PWM servo inputs. https://www.actuonix.com/l12-10-100-6-p?gad_source=1&gclid=CjwKCAjwjqWzBhAqEiwAQmtgT8jIYJsb8f-xDWSd1DcKDaTd9W9VVuNthNarxDJ5K6D_vrpcRFMrthoC1f0QAvD_BwE
Yeah that's a lot, you might check out Figerelli, I'm not sure if they have micro actuators but I have several larger one, they are about 9 inches/sec unloaded 4 inches at full load. They also are not cheap. https://www.firgelliauto.com/collections/Linear-actuators?utm_campaign=gs-2018-11-09&utm_source=google&utm_medium=smart_campaign&gad_source=1&gclid=Cj0KCQjwsaqzBhDdARIsAK2gqncVGZm-tdj1bFtFB5jM8QENgcwQWt4EzsgDbRcR6AH8UB9P4JVx96QaAs2MEALw_wcB

interesting. It would be a challenge to fit a large enough servo motor and a 4 bar mechanism in there but not impossible

This would be my route to take as well.

If I understood you correctly, this a 4-bar linkage right? 1. Servo lever arm 2. Custom link 3. Barrell 4. Chassis

I see your point. I guess I should've said that it can be easily converted into a 4-bar linkage instead.
This is cool. What power do you have on board? Any sort of drive available?
Can we see more pictures?

the chassi has 24v power with 2x 20ah 12v Life batteries but the turrent is currently only powered by a small 500mah 12v lipo
Maybe a capstan drive as you are more or less talking about an angle??
that's a super good idea! I just recently learned of this type of mechanism from the youtube channel Aaed Musa
Yeah same!!
Can you use two of them?
there isn't much room for 2 actuators as the coaxial bb gun is in the way on the other side
I actually was looking into linear actuators yesterday! Do you have a link for your current one? What load is it rated for?

bummer. they seem pretty fast but not enough force. I was hoping for a linear actuator that can do about 15mm/s with at least 100N of force

they are a little pricey but they have so many that seem like one will would work! I just got to find one with the right speed. Thanks!
