I have used the Hobbico locator.  It works as you describe and will likely work
with 2.4 GHz but it is so annoying to have to move the sticks just to keep the
alarm from sounding.  If they had a 10 minute window instead of a 1 minute
window it would be ideal.

Best regards,

This will work fine with PPM, PCM or 2.4 GHz stuff, and you won't have
to do any special programming to make it work --

The lost plane alarm will be activated if the servo channel it's on
stops getting pulses, which is what works with normal PPM stuff and
doesn't work with PCM or 2.4 GHz gear.  However, the transmiter
inactivity signal (which sounds the same as the lost plane alarm) will
still work even with PCM or 2.4 GHz -- if you stop moving the sticks
(or if you go into and stay in failsafe), that channel will be idle
(not changing, though it may still be getting servo pulses), and once
it's been idle for a minute, the alarm start beeping as if your plane
was lost.

And yes, I've tried it.

The downside is that your plane will get upset and start beeping if
you leave it turned on and idle for a few minutes -- like when you put
it down between flights.  Most annoying.  I wish they'd made the
timeout five minutes instead.
