Lost Aircraft Alarm

I’m looking for a lost plane alarm.
All I can find is the lost copter alarm on ArduCopter.
Why is there no similar function in arduplane?

Thanks in advance,
Daniel

This one will get merged at some stage which will add this functionality:

Tbeacon is a great standalone option. Check it out on RCG.

Sounds great, but why don’t use the internal beeper?
With arducopter you can put the ‘lost copter alarm’ on a switch.

Because flight packs often get ejected on hard impact. tBeacon has it’s own battery, total weight ~5g, and can listen to GPS without being dedicated to system flight pack. Long listen and ping time. I won’t fly any of my quads or fixed wing without it, except micro Radian, which is a feather to begin with…
