simple to set up, loud and works fantastically.
Using these in my 250 race quads and I wouldn't fly without one now...essential
Nice buzzer, works like a charm. Using on a HK 260 black widow drone.
THESE DEVICES NEED SERVO PWM SIGNALS TO WORK - THEY ACTIVATE WHEN PWM IS ABOVE 50pcnt SO THEY NEED A SPARE CHANNEL ON THE RECEIVER- i HAVE USED THEM SUCCESSFULLY WITH FRSKY 4&8 CHANNEL RECS MANY TIMES UNTIL ON ONE CRASH THE BATTERY WAS FLUNG OUT SO NO TELEMETRY OR LMA - PLANE LOST IN THE FOREST.

I WOULD LIKE A LMA THAT WILL TRIGGER WHEN SERVO PWM IS -150pcnt THEN ANY CHANNEL WITH "Y" CABLE COULD BE USED AND NOT UTILISE A SPARE CHANNEL.
Makes a lot of noise, also works with 4S (I don't know if it is safe for it). Also beeps every times you connect a battery to your model, and when it's inside (workshop) it can be pretty noisy.
Lo applico su tutti i miei multirotori, si sente a una distanza di circa 200 metri
It only works on a 5 volt power source. Plug it in to a receiver that's running on 6 volt BEC, a 2S LiFe, a 2S LiPo or a 5S NiMh, it will beep a few times when you plug it in, but you simply can't make it work when you activate tha channel. I tested it with a Turnigy AE-45 speed controller. At 6v BEC, nothing. At 5.5v BEC, nothing. At 5v BEC it works perfectly.

But other than that small issue, it works well. Loud little BEEPER (it doesn't buzz at all).

It would have been nice to know the specs before I bought 6 of them for slope planes that run on higher voltage packs.
This is a really usefull little thing which could save your model when you crashed it into tall grass or something like that. I could deffently recomment it for that price.
Le plus simple, le plus lger et le plus efficace des systmes de ce genre. Ne cherchez pas ailleurs ! Le "Be found" (disponible aussi sur ce site et moins cher) ne fonctionne pas avec les bons rcepteurs modernes (c'est dire quips de failsafe).
This thing is not only useful but also really fun. They are loud and work well. if you put them on the outside you your model you have no problem hearing them. I bought 2 and used them as just a noise maker on my plane for fun and they are great. They are an awesome cheap investment for your model to increase chances of locating your model in the event of a crash.
