One for Tomas please........just updated to 3.1 and am now getting twitchy/jittery servos. Head and Tail. All has been good on previous versions including 3.0. I have tried going from 3.0 to 3.1 and also from 2.8.
The spirit did take about 10 seconds to give the 3 head shuffle to show all was good, normally about 2 or 3 seconds.
Any ideas? Thanks

We never saw a similar issue.
Can you disconnect everything unnecessary from the unit?

What is connected to the unit now? Maybe it is outdated, for example GeoLink.

I guess you have connected GeoLink with old firmware. It must be updated to version 1.2.0.

Should add it only does it when Tx on as well

Jeti REX and ExBus.

I've tried a fresh download from different browser but same. The tail also wanders full over to stop.

Can you let me know if something is connected at the RUD signal pin?

Are you using supplied JETI integration cable?

RUD has the two pins from the Jeti Integration cable, AIL has the other. Nothing on RUD signal pin. Been working fine for years like it. Cable is my own.

Hi Tomas,
I have the same problem with twitchy servos after update to 3.1.0
- Jeti REX 3 (ExBus)
- Jeti Ds 16 Tx
- no GPS unit
- I have tried to connect only servos and NiMh battery and the problem is still there
- The old red Spirit is strongly affected (I have two of those and both do the same one more then the other) tail is after 25s fully tilted to one side
- Spirit PRO is working perfectly - no twitching or buzzing
- Spirit II is barely noticeable buzzing in interval ~3s no drifting at all (I wouldn't even notice if I wasn't paying attention)

Kind regards, Robert.

That is very interesting, we are testing mainly with exbus with no problems.
We will need to look into it on monday.

Do you have default channel order in the Spirit unit?
