- This video highlights a linear servo solution put forth by "Sub" Ed Tordahl. This is my take on it. I hope you enjoy!
For much more RC sub info, parts, resources and infomation, be sure to visit my site at www.nautilusdrydocks.com
Thanks for watching!

Simple and yet elegant, a real workaround that can fit a lot of situations, thanks for passing it on!
You sir(and your friend), are my hero. I had nights of headaches about this solution. Never thought it would this simple. Ty ty ty!!!
Great video! This solves my problem of fitting 14.5mm vertical travel into a 15.5mm space without having to design an elaborate bent rod system.
A very simple but brilliant solution. Awesome and thank you for posting this.
Simple and fantastic solution Bob!!! I had a space issue for the aft dive planes control in a friend's Robbe U47 which I am overhauling and converting to static dive.

This is a scotch yoke mechanism... Actually a scotch yoke can rotate 360, but this is a great implementation for a servo.
neat ! can't wait t try that out on something....thanks for posting
It's just what I need for I project. Thanks!
Great video..loved the idea
Simple and efficient. Thanks
U r great !!! That s what I was serching!
Thanks for sharing new ideas ! 😉
you save the country, thank you so much
Enhorabuena! Buena idea, me gusta :)
Wow, that is amazing
love it ! excellent
what a brill idea.
Great Stuff man thanks!
been around for years, got these in my boats from the 90's
clever, in my scratch subs i put the servo far awat from the seal to avoid desviation in movents
Brilliant!
perfect!
Verygood bro👍👍
I love simple!
Kuods to you mate, seen it here first
What is the silver part called? The part that is attached to the servo wheel and has the brass rod going through it?
Hello Bob, can you please post a link to that STL file? I will be 3D printing this out for sure as I have a could place I could really use this!
Hi thanks for the idea. What type of nut connector are you using? The one on top of the gear connecting to the rod. Thanks
PUSHROD Linkage Stopper SERVO CONNECTORS 2.1mm
If it was bent to a 45 would you get more dof?
Nice and if you want a longer stroke you can use a long servo horn and relocate your accessory 🔵🔵🔵👍👍👍😀😀😀🔵🔵🔵
thanks ;)
linear velocity changes due to rotation angle, so you should use parametric motion equations to get a constant speed or a uniform acceleration
Hi do they sell the mini linear acurators kits on the Google website
Did you get the bent rod readymade or made it yourself, if you've made it can you tell me the machine's name that can do it in a cost-effective way. Thanks
That's a simple bend, a plier would work. Or a vice. But there is also bending tools for push rods
Great idea are you selling yet thanks
GREAT! What's the name of the metal cylinder on the servo? Where can I get it?
"linkage stopper" or pushrod connector. Should be available at any RC airplane parts supplier.
Do u have a RC submarine that shoot
Do you think this set up with the dial would be possible to operate a manual choke in a classic mini?
I wouldn't use this setup. I'd invest in a proper linear actuator.
Use large wheel for longer movement
are these still available?
Very nice design. By looking at your configuration allowed me to design, in my head, a variation of your design that I need for continuous reciprocating motion. I need that rod to continuously reciprocate. I can see that one change would be is to raise the rod and turn it 90 degrees and have it come out of the center of the connector on the servo crank, clearing the rod for a 360 degree rotation. The servo would have to be modified to continuously rotate and that would satisfy my requirement. I am animating the swinging of a bell on a G scale steam engine. This would work super and thanks again for the idea. Robert Brown.
wouldn't work that way, unless you flex the rod or add another linkage.
What would work, though, would be to offset the bushing outside the rotating diameter of the servo wheel and make the end bit longer.
@@alexandrumoise1511 It should be possible. Tested and simulated it in fusion 360. You need to move the "fixed busing" all to the right. It will then allow you to turn the servo 360 degrees without any crash. Sorry for bad explanation, but it is possible.
@@asbjrnrrvik4449 yea, all to the side. It's what I meant in my comment.
How is the 3d printed part attached to the servo?
I just used some CA glue. If the servo fails, the linear adapter is cheap enough that I just make another one.
Wow ~
what's the name of the parts please?
Much interference noise from Metal-to-metal parts?
Hi are you selling these yet thankyou
Hi. Can you share your 3D model ? thanks
Fantastic video. Do you have any linkage connectors left?
Magnetic linkage connectors? Of course. Available on my site at www.nautilusdrydocks.com
@@RCSubGuy I cannot find them on your website. I need at least six
Since you have a 3D printer, why not just make up a simple rack and pinion?
now you can lock your drawers
Straight, not linear. Could be made fairly linear by programming your transmitter though.
The description of linear is not in terms of proportion, but direction.
This is not a genuine linear action along that axis as the rotational arc of the servo disk mean that the motion distance along the pushrods axis reduces as the servo moves from its centre point !
Seriously?... sigh. The force is linear. It is, therefore, a linear servo.
All this is, is a rotatory tattoo gun made with RC parts.

This is NOT(!) linear unless you correct this in your radio! Why would somebody do this, instead of taking advantage of long beding lengths.
Because it's simple, reliable and easy to implement. The description of linear is not in terms of proportion, but direction.
