Most Helpful Customer Reviews

Installation instructions are seriously lacking. You must solder two (20 ga) leads into the battery circuit. The rest are plug ins. They instruct to plug the Y cable into throttle channel in RX. But you can plug it into any channel that gets a lot of use. Am using this alarm in a glider. Throttle can go unused for minutes. So I plugged into rudder port, to avoid false alarms. Have set battery monitor for 3.7. Works great. Strong alarm signal. Discovery alarm needs aux1 channel. But aux 1 is taken up by SAFE PANIC MODE. So I use signal monitor instead for discovery...if needed.
Works great!
I use this for its discovery setting.
I fly in an area where there is tall grass, and I once took almost 30 minutes looking for my quad copter.

My reason for giving this 4 stars, is that for some reason, it no longer works.
Just having it plugged in makes all four red LEDs blink, and the buzzer makes a ticking sound at the same speed as the blinks.
I do not know what could be going on, so for now, I'm leaving this review at 4 stars, until I figure out if it's user error, or some defect or something.
Really nice to have as a backup, can be set as both a transmitter signal loss and battery voltage alarm at the same time. super cool beans
