I've tried to configure the spirit governor.
It's a HW V3 esc in airplane mode.

In my radio, I've set 60% 2600 and 100% 3200 flat throttle.

In the spirit gui, I've set max speed to 3200.

On the bench, it spools up to iu1 2600 and up to iu2 3200 when selected.

If I hit throttle hold for 2 secs then turn it back on, the head speed drops to around 1500 and takes 10 secs to get back up to 2600. Iu2 will no longer work; I can see the target in the gui is 3200 but the governor makes no effort to reach that and remains at 2600.

I have to disable the governor to make it work again.

1) Why does it take 10 secs to reach full head speed again? Surely this should be 1-2 secs following a bailout.

2) Is this a bug?

If I try this with governor disabled, the motor speed changes instantly as expected so it's not the esc causing this.

Hello,

when you hit Throttle Hold the motor should instantly turn off normally.
Do you use some Delayed function for the Throttle channel?

The motor should start spooling up always in the normal procedure once you hit Throttle Hold. This is correct behavior.

You can also program ESC for helicopter mode but governor must be turned off, otherwise unexpected behavior will occur.

The bailout is engaged only when Throttle Curve is above 12%, in other words - it should not fall under this value. Otherwise slow spoolup will engage as described here:

The motor slows down normally. It just takes longer than 2 secs to spool down. This is all normal.

I see! I did read the manual but seemed to have missed this.
I'll add a separate switch at 12%.

This is what I would like to achieve:

Spool-up should take about 10 seconds to reach required head speed.
When hold pressed, motor stops.
When hold released, <2 seconds to reach required head speed.

But I cannot get this to work!

When hold pressed, throttle is set to 13% as seen in diagnostic tab.
The motor slows down and stops because I increased min throttle in gov setup until it stopped.

When hold is released, motor spools up slowly, so i increased to 250us to make it <2secs to reach full speed again, but now when starting from ZERO throttle, the spool up is much much too fast (3 secs) which means i will not be able to control the heli on the ground!

How can i set this to 10 secs spool-up, 2 secs bail-out recovery, just like Hobbywing Gov ?

Hello,

for the first time when you are starting the motor it should be always slow.
But once you will use autorotation bailout and throttle hold was not really at 0% it will spoolup quickly.

The only solution is to have switch that will really send 0% throttle curve. Then the autorotation bailout will reset and it will spoolup slowly.
Possibly it could be programmed in the radio.

When i set throttle to 13%, motor stops, when setting it back to 80% the motor spools up in 2 secs. (as expected).

When setting motor to 0%, then back to 80%, motor spools up in 2 secs (incorrect).

I'll try to take a video of this and the settings I used.
