Spirit System

Did you tried to redownload the file or just updating from the same file all the time?

I am not at home until may 7. i will make this trials then.
But I do not undesrtand what do you mean about changing the fbl unit doesnt mean nothing!!!
For a final user is EVERITHING !!!

I conecta the xX fbl and no servo vibrations !!! Thats a lot

I redownload 100% because i Was in the field when this happened

It is possible that elevator behavior that you have posted is correct. It depends on your settings how the cyclic is behaving, unfortunately from the video I can not see all the details.
This can't be compared with other FBL as each one is working differently on the ground.

But jittering of the pitch is not correct of course. This can be caused by Gyro Gains.
Can you observe the problem on all cyclic servos or just elevator servo?

Mostly 0% Gyro Gain is not good, because rescue/stabilisation can be enabled/disabled on its own. So then you can see this very strange jittering. You can check this in the diagnostics tab.
It is also important that you can see +/-100% collective pitch travel (not more) in the diagnostics tab. Values in the transmitter are not important.
What connection type do you use?

I am using standard receiver.
What gyro value you recomend to actívate rescue?

I cant see wich servo is causing the jittering.

Please. You can see My settings in a file that i posted in other thread of the 600L

If you need other info or video just tell me

I will be back home may 7

Think you

Value for the rescue activation should be always the opposite for your normal flight mode.

As it was mentioned you can try to enable Cyclic Ring (tuning) to verify if the issue will occur in this mode too.

I can't see your settings at all.

Please, look at the file. almost sure it is the last config
