Not sure why but I tried:

• Governor Response: 5
• Holding Performance: 4

I had some terrible headspeed hunting when doing Fast Forward Flight.
Because of the wind, I had to give small collective inputs to counter the change in height.

You could hear the headspeed hunt for the target rpm.
From the tooltip I understand I need to go down with Governor Response.
I'll try 4 - 4 next flight.

I recommend to try our alternative tuning method described in the manual.
So starting with Holding Performance at 1 and gradually increasing Governor Response.
With this method you can tune both parameters much better as you will clearly see what they are doing.

So starting with Governor Response around 3 and Holding Performance at 1 may be good to start.

With banks you can then try Governor Response 3, 4, 5 very fast and find which is performing well.

Thx, I'll start over and learn.
Using 3 - 1 next flight.

Hmmm, I had some weird thing happen to me.
When I hit throttle hold to go fly, it seems my headspeed went to 100%.

It looked like the governor did not engage and the ESC seen my 100% flat TC.
I changed to Stunt 1, which is 96,5% and back to Stunt 2 (100%).
Now the headspeed was governed.

With 3 - 1 setting I could still hear the hunting with small collective inputs.
A full collective pitch pump however seems to be fine.

I set for 3 - 3 and 4 - 4 for my next flight using bank switching.
Also did a throttle calibration on the ESC again.
Probably not needed because it has been done before.
Just to be sure.

For some people this issue is happening when throttle is not calibrated correctly.
What is value of the throttle in the diagnostics tab, when there is 0% TC?
Do you see Requested RPM correctly?

Also you may try slower spoolup rate.

I checked the diagnostics tab again.
It's perfect and spot on!
Using a linear TC from 0 - 100%, stick all down is a 0 on diagnostics.
Stick a tiny bit up and you see the diagnostics climbing as well.
Stick all the way up and diagnostics goes to 100% as well.
I can't get this any better.
And yes, requested RPM is exactly as expected.
If I let it run briefly, it also shows actual RPM.

Oh, I'm bench testing with a 3S lipo, if that matters.
Flight lipo is 6S.

Again I had a very high headspeed on spoolup.
Switching briefly to Stunt1 and back to Stunt2 solves it.
I'll try slower spoolup again (Governor Mode - Electric), because this is very annoying.
I don't recall I had this issue with "Governor Mode - Electric". We will see.

While flying for sure it did more hunting with 4 - 4, compared to 3 - 3.
Very handy using bank switching for testing!

Tried 3 - 1 and 2 - 1.
Did most of the flight with 2 - 1.

It seems the lower it goes, the more comfortable the governor is on my X3.
Are these numbers completely out of whack?

Next flight 2 - 1 and in the other bank 1 - 1.
Let's see what happens.

Next time I spoolup I'll tach the head, takes out the guessing part.

Thank you very much for your comments.

Your values are normal, if motor is strong enough then only small corrections are needed. If configured values are too high then problems with unstable headspeed can occur, so it actually can be worse.
