I also check other website and so it seemed the HXT900 is very prone to jitters. I crash my aircraft using this servo twice. Although on the bench , the servo doesn't jitter but in the air, the aircraft was flying fine ,then it went out of control mysteriously ! No HXT 900 servo on any aircraft for me!

I have the HXT servo, they jitters like crazy.

Or just use analog servos

It really works!!! Thanks a lot, we had been working on our capstone project and we had servo jittering as well, and it was inconvenient to solder the capacitors in. Well, until we found your video. Bought some small ferrite cores, and it worked like magic!

Awsome vid! Gunna sort mine out today! Cheers dude

man you are sent from above . perfect fix. didn't believe my eyes . THANKS

I have a ferrite rod from a radio kit. Im itching to use it for something

thats such a weird and dumb way to to do it. now your cap is gonna snap off and break after a short while. why the hell would you have just reposition the terminals on the bind plug, cut the wire into 2 and directly soldered the cap on to the end of the 2 wires. that way you can secure the cap down to the vehicle.

They are twitching cause they are scared of corona.......LOL LMAO

I use it too in my bicopter. When the bicopter is not being armed, the servos go very well. But when that is armed, in throttle (over min throttle) the servo moves slowly to the left and the right 0 not center - whats; wrong?

Helps a lot! thank you very much!

Why not just connect the cap to the wires.

I'm getting a little jigger from my high-tec 645 what is it you're using that you're wrapping around the wire exactly

Carona servo 🤔

Crazy thing is this was 9 years ago

Awesome. I had the same problem once but the noise was coming from the external bec. After adding a little core with 4 turns the servo twitch stopped. The servos were just regular analog though. I've now noticed that some of the newer UBEC's already have the core installed on them.

Awesome 👍 ill give it ago cheers

How do I make one or buy one?

You deserve 1.million subscribers

What is it that you put on the wire?

thx this helped very well

How can I get this

My helli weighs about the same as that ferite ring

How about if I make 4 turn? The more the better?

The Green Ring , What is this ? name, please . thank you

Would a capacitor in parallel work the same way..? Thanks!

Hi, just came across rthis interesting video while trying to solve a servo interference problem on a model railway. I have numerous 9G servos on the layout and some get interference (I believe) from the track power fluctuations when locos run over rail joints or points (turnouts). Would this solution help? Cheers!

Do you have a specification on the ferrite core? And a vendor recommendation? Amazon has some but they are one once, which much larger than yours.

Me: working on a small personal project, trying to relax and forget about the ongoing pandemic Servos: 0:08 CORONA

Is that a metal core?

Didn't expect it to work ... had ZERO hopes but IT WORKS LIKE MAGIC! lesser and lesser jitter with every coil ...

This solved the issue I had with my servo. Thanks!

thank you SO MUCH

does the circular core has to be a magnet?

Amazing. Just fixed this issue being caused by a crossfire receiver antenna jittering a servo. Put a ferrite ring on it, perfect!!! I think it’s the cause of my in flight shakes

Can I find human microchip transmitter and receiver as well?

Another solution: buy decent servos to begin with. the blue little things only cost $5 or less but you get what you pay for.

There's also another issue. If you put a digital servo on that receiver (not digital) the servo (HTX900) will go into analog mode wich is not it's best mode. You should only use digital servo when you have a digital capable receiver or FC. In fact most modern fc's you can set the puls speed/width for a digital servo. In every other case the digital servo will be in analog mode which causes the jitter.

Thanks for the solution, would you kindly tell me how to remove the noise of the servo motor

You are awesome thanks for this mate 👍👍👍👍👍

Thanks great video mate!!!!!!

I'd give you 10 thumbs up if I could. You saved my day. Thanks!

what size it the transmitter? and is it 100% waterproof? will it also transmit through soil?

Ummm.... while it solves the problem, adding ferrite core will puts a considerable weight to the overall final build.

Impressive....worked perfectly for me....thanks man!

For those that after trying this still have the same issue: you should try using a capacitor between VCC and power supply and it should fix the jitter.

Does anyone know why my servos twitch when i touch metal in the car with something metal?

I have same problem, but it started happening after two weeks of normal operating, what is up with that, are my servos damaged (i highly doubt that) or is something else going on?

What material is that O ring made of?
