Plug it in to a spare channel on your receiver and the Buzzer can be activated by a switch on your TX. Switch the buzzer on to help locate a lost plane.
This device works extremely well with my FrSky Taranis/X6R combo (unlike the earlier in-line lost model buzzers which I could never get to work). The 'Morse code' buzzer is quite loud in the open air and should help my find my small models in long grass. I bought three of them and will be buying some more. The only downside is that you need a spare channel on the receiver to dedicate to the buzzer.I have it set up so that CH 6 will activate it, and that works just fine. The problem is that it will randomly activate during flight - sometimes it is on almost continuously.simple to set up, loud and works fantastically.Using these in my 250 race quads and I wouldn't fly without one now...essentialNice 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 metriIt 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.
