Sanwa Exzes X problem

[Npdp72]

I have recently bought a used Sanwa Exzes X with RX-451 receiver and I find I get jittering / twitching of the steering servo at the neutral position.
I am using a Savox 1258 servo (which is brand new) and have tried switching over to my spare Savox 1258 and I get the same thing.

Could this be a problem with the radio gear?

Can anyone shed any light on why this is happening?

I'm using a LRP SXX V1 ESC if that makes any difference.
I know of someone else at my club that uses the same radio gear with the same servo and he doesn't have this problem.

Thanks in advance for any help.

Check to see if you have a range problem as well !!

What would a range problem indicate?

It could indicate an aerial problem.

Borrow your friends’ aerial and see if the jittering goes away

I'm running an EXZES X with a 1258 and again no problems.

Just a thought. When you look at SET-UP [MOD] TYPE what do you have set? Mine is set to FH3. If I try the other modes (FH2, FH3F) I too get jittering.

Is it the RX-451 (with the mostly brown sticker) or the RX-451R (mostly black sticker) receiver you have? If it's an R and you have the transmitter set in high response mode that can make servo's get a bit confused if they're not compatible with SSHR.

What happens if you swap the servo and ESC plugs in the receiver? It might be a faulty/worn pot in the transmitter on the steering stick. If the ESC starts jittering about after you've swapped the plugs over I'd guess at it being the pot.

Try binding your car to a different model number on the handset, like 10 or something you've not used and se if that solves the issue.
A mate did it for a glitching speedo and it worked. Strange, but worth a try
