9256 twitches with Spartan on bench set-up. is this normal?
I updated the firmware to the latest version from the Spartan website. when I set it up the servo twitches like crazy, even with no inputs. I tried a different servo and it did the same thing. I'm trying to set it up using a 14mz. My atv's are 100% and my gain was set to 70% on the bench. I already put in a service ticket but I wanted to see if anyone knows what could be wrong. Just to let everyone know. I'm using a fromeco 4800mah battery, arizona reg, and 8ch fasst rx. I had a spectrum voltage reg but I took that out to make sure it wasn't the problem. the battery was charged for the bench set-up. So I know it's not the battery. what could it be?

Same thing, constant twitching. I tried using my align 2 in 1 and using a step-down reg on the servo and it still acted up. I then tried my 9257 from my 500 after i changed the settings using the flashlink and it still twitches like crazy. what gives?

you do know that after an update you have to set the gyro up again?
So you have to select the correct servo type etc etc.
I bet thats whats going on.
Incorrect servo type, and the the gyro is sending the wrong pulse width to the servo.For the love of the hobby

rudder gain is definately plugged into ch 5?
Do you have the usb programme cable?
If you do, then have a look at what actual gain the gyro is seeing in the software.
It will tell you at the bottom of the programme window.For the love of the hobby

Rudder gain is plugged into channel 5. Yes, I have the USB cable. I have to say Spartan(Angelos) replied quickly to my open ticket. I did a diagnostic test as per what Angelos told me to do. It's seeing a gain of 35%.

hmmm, well all sounds correct.

Very odd that its only after the update.
Have you tried re-loading the update file again?

Besides that, Im out of ideas as to what it could be For the love of the hobby

I haven't tried to reload the old software. Angelos told me to send to back to have serviced.
