A picture speaks a thousand words, and all that...:nevreness:

You can ask Elliot at Hexcam for advice with your ops manual.

Ah, so it's high frequency vibes with a little flutter here and there. That is usually an out of balance prop or motor. You also mentioned seeing one of the arms wobbly in flight which is a clue. Do the vibes change when you increase/decrease the throttle? If not then it's the Zenmuse balance...

If you would show me the jello video (from the GH4) I could probably see where the vibes are coming from.

It's not the length that counts! :nevreness: So are you going to balance your props now? It's a good skill to learn.

Ha! :nevreness:

That'll be the problem then. Have a look at those blades.

Easier but not entirely precise. Good enough for me. Those little electronic scales are great for weighing components and the like. You can also use a 'tail blade' balancer for an RC helicopter. Works like a seesaw.

Yeah, that video is pretty good. Nice find! The vibes must be coming from the motors or props then. Can you show us an example of the jello on the video? We can usually tell what is causing it by the frequency of vibes.

For foldable props you can just weigh each one (as a pair) and check each blade weighs the same. I've just spent the day doing that to my S900 props.

Just watching the gimbal whilst powered up is not checking the balance. Does the GH4 stay where you put it with the power off? Here's how to balance a Zenmuse:

Are you sure the gimbal is well balanced? How about the blades/props? Have you checked they are balanced also?

What help do you need?

All depends on what system you have. I can take stills via a switch but can't adjust other settings. No need really as you just set it manually on the ground. You'll soon learn what settings you need by practise.

Did you read through the post I quoted? Have you deactivated X1 for gains adjustment in the other screens on the assistant?

Huh? What aircraft and electronics are you talking about? Just looked at the MLP6DSM and you may well have to adjust the trim each time as it is a very basic transmitter without memory.

As above, turn off the gimbal switch screen, not needed for the Zenmuse. There's some help here. It says you should calibrate the X1 channel.

Ouch!

Sounds normal to me. It's a safety feature of the NAZA to prevent inputs on the ground (apparently).

Ah, I just had a look at the mini Zenmuse and it doesn't have the same channels on the GCU as my larger Zen Z15. Ignore what I said before.
