Disarmed by lowest throttle stick position

Hello all,

I’m flying a quadcopter with stabilized mode.
I’m experiencing that the quad copter is disarmed by lowest throttle stick position for several seconds.
Is it a default setting? If so, do you know the reason for that?
If I don’t want that setting, how could I change it in QGC?

this seems to be the recent px4 firmware behavior. Probably good for beginners, but really confused experienced pilots.

There are different things you can configure, like auto-disarming or the use of an arming switch: https://docs.px4.io/master/en/advanced_config/prearm_arm_disarm.html

Thank you very much for your verification. I think if I have a option to deactivate the throttle stick lowest position disarming, that’ll be helpful. But, so far I cannot find how to change it.

It seems that the auto-disarming is for the disarm after landing as described below.
“COM_DISARM_LAND: Time-out for auto disarm after landing. Default: 2s (-1 to disable).”

But, even before landing, if the throttle stick is at the lowest position for several seconds, the quadcopter is disarmed. So, I think this is different from the auto disarm mentioned in the page (https://docs.px4.io/master/en/advanced_config/prearm_arm_disarm.html).

Correct, there is now also COM_DISARM_PRFLT

Thank you for your reply.
I looked at the default vale for COM_DISARM_PRFLT. It’s 10s.
But, if the throttle stick is at the lowest position for several seconds less than 10s, the quadcopter is disarmed.
So, it seems that different setting disarms the quadcopter. I don’t know what disarms the quadcopter.

COM_DISARM_PRFLT: Time-out for auto disarm if too slow to takeoff. Default: 10s (<=0 to disable). (https://docs.px4.io/master/en/advanced_config/prearm_arm_disarm.html)
