Product details
The iFlight YR50B_S is a self-powered lost model alarm designed to help you locate downed FPV drones, even if the main LiPo is ejected during a severe crash. Weighing just 4 grams, it is a critical recovery tool for everything from freestyle quads to long-range rigs flying over dense brush or tall grass.
Key features
- Independent power: Triggers a 100 dB alarm and flashes dual LEDs when main drone power is abruptly cut.
- Auto-charging: Replenishes its onboard battery via the flight controller's 5V line during regular flight.
- Dual purpose: Functions as a standard Betaflight status and warning buzzer when the drone is powered normally.
- Quick silence: Features an integrated push-button to easily disarm the alarm after you recover the quad.
