Pixhawk beeping when switching


I used a Chinese close of the 3DR before with the spectrum DX8.
When switching between flight modes no sounds.

Now I am using a genuine 3DR pixhawk with Futaba 14SG sbus receiver.
When I switch between flight mode there is a beep from the pixhaw.

Is this normal?


Yes, this was added as of 3.3 to indicate the copter has switched modes. If you hear two beeps when switching modes it means it could not switch to that flight mode and will stay at the previous mode.


Thanks Mike
