Making a rc servo spin continuous 360 and hold position.

- This video details how to make a regular RC servo hold its position after moving the stick on the transmitter. This can be achieved in a couple ways but this video will show how to modify your servo to accomplish the hydraulic construction equipment stick movements.
Hope this video helps. If you have more questions please leave a comment and I will answer your questions. And if you want more details I can create a more detailed version.
Thanks for watching and hopefully we can get back to the construction videos! There will be some new machines coming!

Thank you sir!! Very usefull, and it worked great on my little 9g servo too.
Glad it helped
I love how he started! Great video!
Thank you!!
Would this modification create a continuous rotation servo or just a 360° positional servo? Also how much does this weaken the torque?
Great questions. When I say 360 I mean that it can spin continously over 360 deg. So you can use it as a substitute a motor. As for torque you will loose some tongue but I have not tried connecting it to an esc to see if it reacts the same way. This method just allows you to use a servo like a motor without having to use an esc to control it. So torque is lost as the potentiometer does not know where to hold anymore. Hope that explains it.
Great Idea. Thanks
This was awesome thanks
That tab on the main gear, no need to cut off, it pops right out with a center punch or even a small nail 8-)
good to know. I wasnt sure if all of them come out or had to be cut off. . thanks for the tip! 😀
awesome tutorial man
you got a new sub bro
Thanks. Glad you like it.
i'm in search of a continuous rotational servo that has a brake. i'm using it in a winch application. i need to be able to hold a load when my control is in a neutral position. is there such a thing?
Reefs rc does make them.
I removed the pin that goes to the potentiometer on a 360 servo to make it spin, but now it spins for a while, before it slows down to like 20% speed, unless I stop the rotaion from the radio, and start it again. Any clues as to why this happens?
You will need to rotate the pot till the motor stops spinning and make sure it does not move. I use glue to hold it I place. Then you can connect to a reciever. It should not spin but if it does you might have to adjust the centering for it to stop. The endpoints ts decide how fast it rotates. Let me know if that answers the question.
Hey so far best and easiest I've seen, I'm not new to RC but I am new to using servos for winch's I've seen some guys use ESC and even separate batteries to power there servo is that really necessary, trying to understand the purpose. Plus my servo does not have a pin on the gear.🤔 I thought I would just plug it in to the 3 channel on my receiver. Using your simple steps. Avoiding the ESC and an extra battery. Like I said I'm no whizz when it comes to electronics stuff🙏✝️☮️🏜️ help
Good video. Mine keeps spinning 360 degrees. All I did was drill out the plastic inside that main gear that was shaped in a rectangle. But I didn't glue mine. Sounds like that was my mistake.
Hey, thnx, woks for me well too.
Glad it helped.
Can the servo be 360degree with position control?
Yes it can but it will not hold a lot of weight. But it will hold in position where you leave the servo. Stick will stay centered but servo will stop where you last moved it.
The fact that the unmodified servo returns to "home" when the joystick is released is a function written into the program code or the joystick electronics. Normally an unmodified servo will move to where it's told and stay until it's given a signal to move somewhere else.
To state that the servo "wants to go back to home" on it's own is quite misleading.
Also, why was the physical stop left in place but the feedback pot disabled?
Hey. I'm in the opposite plight right now. I soldered in some new wires for my Slash's steering servo, and now it turns as shown in this video and wouldn't go back to centre or hold position in accordance with the transmitter's steering control.
Any fix to that? Thanks.
The servos should not have any wires soldered or changes. This modification is not designed for steering applications. I qould put the wires back the way they were to keep the steering as it was. Or just get a new servo.

Thanks for replying.
It is one of those servos that are used for RC car steering and had badly damaged wires. So I replaced them with the new ones and the problem started.
The mechanical output wouldn't come back to centre promptly as it used to and the entire control is somewhat finicky.
I'm inspecting what went wrong. Now, I think I've found the issue. The potentiometer isn't connected to the servo saver (that's the output gear right? I'm sure no parts fell off while assembling, so I don't how I can properly connect those two.
Please let me know if you need more info.
To make it clear, I didn't attempt to actually modify the server to spin 360. Just happened to replace some bad wiring and it ended up like this. I came across this video while trying to find a fix.
you might have to check your wire connections and how you soldered them. It might be a wire is touching another one and causing issues. the signal wire is the one that tells the servo what to do based on your input. so that could cause an issue. when you start messing with the guts of a servo it is important to not forget how it went back together. At the end of this it is probably better to get a new servo as they are pretty cheap. check out the 20kg or 25 kg servos. they have lots of power and are relatively cheap.
@@RCConstructionHobby I just managed to fix it! I had actually forgotten to insert a part that connects the potentiometer to the output gear. So, your advice to remember the steps to retrace is sound. Thanks for all the help.
What causes a 360 servo to always twicth like it want to spin on its own? I have to use the fine tune steering adjusters on transmitter to kind of stop them from moving on there own. Any help appreciated man
If it is twitching means the potentiometer was not set perfectly before gluing. I would suggest umgluing and adjust it to be perfectly placed and then glue and let the glue dry before closing things up. It's not a perfect solution but the other way to do it is is to remove the wire to the potentiometer and add an esc. But it defeats the purpose of just having a servo.
just wana ask my servo wont go back to neutral its a 360 servo. it holds where u steer. not like other servo it goes back to center. any servo suggstion for good steering?
For steering you do not want a 360 servo. The 360 servo is really for driving wheels or tracks. It spins continously and will not return to center. If you want a servo for just steering look at a futaba 3004 servo. They are cheap and work for steering on light vehicles.
Iam 2 years to late watching this clip. Really need this in my build bud iam to late :(
Never to late. You can always start a new project.
hi so when I have the servo that I made into a 360 mode when I plug it into the receiver it just turns and turns I can change the direction but it just turns I must be doing something wrong
You need to superglue the potentiometer in the betray position. So before reassembling plug in the servo into a servo tester to make sure it is in the neutral position and does not move. Then superglue and make sure it dries before you use it.
@@RCConstructionHobby thanks I did glue it but the motor just keeps turning I’m using a fan model low profile digital maybe I’ll have to get some different type of just give up thanks for your help I do love your video through I’ll keep watching 👍
Mine want stop spinning at all I need it to go left to right no 360
can you put a rubber band
I'm not sure what you mean by putting a rubber band?
U know u can push it down
Not sure if understand by push it down? What is pushing down?
