This buzzer is loud!!!

While flying it lets me know if the battery is low... great beeper.... but it is loud which is good if I ever lose it.

Don't lose your drone again

I consider these as essential to every quad I fly. They work great as a standard super loud beeper but if your battery ejects in a crash or you get stuck somewhere and you can't find it for hours (up to more than a day) the unit still works and will help you find your lost quad. A little big (about the size of a 1000uf cap) so plan your build accordingly.


have a bunch of these in different flavors and models/mfrs. prefer this one for most builds over the micro USB version (ViFly Buzzer), since you can easily wire to the FC. the micro-usb version has its place tho as a quick tape on finder for mine or a friends quad.

Perfect fit

A must have when setting a long range rig.


Nice to have
