Buyer should be aware that there are at least 3 versions of this alarm sold by Bangood under the same name. If they all work as well as mine they will be very valuable to the RC Modeller. My name is Phil Elliott and I have written a user guide with an illustration so that non-Chinese modellers can understand the one that I received - let's call it v3. Chinese modellers can get the guide from Bangood I believe. The instructions are shown in the attached jpg picture. I installed mine in a flying wing and attached ch2 through the pcb and ch6 into the other end. See the attached picture. The beeper is efficient with a low tpd in the 10's of mW region. Beeper is ordinary to good loudness level and the LED is pretty bright too. See the pictured too. All the best from down in Tassie. Phil Elliott

With a low price, you can simply find your loved plane in case of crash. At the moment there's not user manual, but I published an image to explain how to plug it.
