Feature request

Is your feature request related to a problem? Please describe. I'm always frustrated when my copter crash and no buzzer is played. Even though I have installed "vifly finder 2", it wont get triggered when copter crashed with battery connected.

Describe the solution you'd like There should be parameter to give user choice when to trigger buzzer/Lost Copter Sound. Parameter should be like Play Lost Copter Sound. with below options []Battery Fail-Safe []Radio Fail-Safe []... And user will tick particular or none or all options.

Describe alternatives you've considered Right now I am trying to set radio Fail-Safe from radio to output particular channel and in Ardupilot parameter I am setting that particular channel option as Lost Copter Sound.

There's an auxiliary switch option "30" / Lost vehicle sound. Any reason why this can't be used?

@rmackay9 yes it works, what i mean if it crash and no radio signal then how can we find and trigger Lost vehicle sound? What I want is, there should be some paramter which will trigger Lost vehicle sound if it encounter any failsafe, Battery Failsafe/Radio Failsafe.

@mrnams If you have any failsafe the vehicle will do lots of failsafe beeping. I'm not sure why lost vehicle beeping is better than fail safe beeping?
