Hi guys
I have a problem with the servo twitching in my HPR C5009.

Some relevant information:
Servo: Savox 1251MG Low profile Digital
Radio system: Flysky FS IT4
I use a 6V NIMH battery to power the RX

All parts are brand new!

Here is a video of how the servo acts:

I have tried 3 different servos, and the all act the same way, so this should not be the problem. I also tried two different radio systems, and they gave the same result. I should although mention that the second radio system was also Flysky FS IT4.
I also tried using a BEC to make sure the output is 6V, but no luck there either.

Does anyone have a suggestion to what might cause this to happen?

No, I used a different RX, so that should not be the problem. If the radio/RX is the problem, there should be a lot of Flysky systems out there with twitching issues!=)

I had a similar problem with an onroad car. I had mounted my rx on top of the servo, once I moved that the problem went away. Have you tried moving the rx away from the servo?

I bought a savox a while back and it did that right out of the box. Not quite that extreme but its noisy and has a slight twitch. Ive had better luck with 10.00 servos from hk.

I had the same issue with a 2 different brand servos on my cat. Someone on the forums here told me to get this and never had problems ever again. I don't even hear the servo anymore when it's in neutral position and all the movement and glitches went away. I am 100% satisfied with this item I'm showing you

hmm that don´t sound good. But in this case it doesn't seem to be the servo causing the problem, as three different servos gave the same result..

that might be a solution! Thanks, I´ll look into it.

I think I hav found the solution. This little cute think came with the radio system:
98385

And once I plugged in the servo to it, it seems the glitching issue went away:-) I'll post my results once I get some further testing done!
