Vifly Finder Mini is a small beeper with its own battery used primarily for finding a crashed drone. The mini version measures 19x11x12mm and weighs 2.7g. It also fits smaller drones. The beeper can be activated manually, via a switch on the radio and betaflight, via the PWM channel from the receiver, or it will start beeping automatically when the drive battery is removed. The beeper's own battery is used for this. It is recharged in flight from the control unit, and the beeper is therefore completely maintenance-free. To better find the drone in the dark, the Vifly Finder flashes in addition to beeping.
