PIxhawk wont Disarm after Landing

Is chibios necessary?

ChibiOS is better than Nuttx

Do I need to auto tune again? Or just copy my values from my last auto tune?

must try and see its working or not iā€™m not tried before

In general ChibiOS does run better (runs faster and more regularly) than NuttX but I donā€™t think it will make a difference in this case. The move from NuttX to ChibiOS doesnā€™t require any changing of parameters or re-tuning.

Once the motors have really slowed down it should not respond to the yaw input.

Should I change FC instead? How about this?

What problem do you feel?

Today had the same problem with Arducopter 4.02 fw at Cuav pixhack v3x FC. Couldnā€™t solve it, just assigned aux channel to Motor emergency stop, and then can be disarmed
