ReadytoSky Mini 5V Lost Model Buzzer – High-Decibel Recovery Alarm
Never lose track of your aircraft again with the ReadytoSky Mini 5V Lost Model Buzzer. This compact, high-output audible alarm is the ultimate insurance policy for FPV drones, fixed-wing planes, and RC vehicles. Designed to trigger a loud, piercing alert during a signal loss or a crash, this buzzer helps you locate your model in tall grass, thick brush, or out-of-sight landing zones.
Equipped with a pre-soldered JST Female Plug, this buzzer offers a true plug-and-play solution for flight controllers and power distribution boards. Its ultralight footprint makes it an essential addition to even the smallest micro-quads, where every gram counts.
Key Highlights:
High-Decibel Alert: Engineered to produce a sharp, clear tone that cuts through ambient noise, making it significantly easier to recover "lost" models.
Plug-and-Play JST Connector: Features a standard JST female plug for a secure, solder-free connection to compatible pins on your flight stack or receiver.
Ultralight & Compact: Small enough to be tucked into tight frames or taped to an arm without affecting the flight dynamics or center of gravity of your drone.
Low-Power Efficiency: Optimized to run on a standard 5V rail, ensuring it won't drain your flight battery while providing maximum volume.
Multi-Purpose Functionality: Can be configured via Betaflight, INAV, or ArduPilot to act as a low-battery warning, a lost-model alarm, or a status indicator (arming/disarming).

Pro-Builder Tip:
To get the most out of your buzzer in Betaflight, head to the "Configuration" tab and ensure "Beeper" is enabled. You can then assign a specific switch on your transmitter to the BEEPER mode in the "Modes" tab. If you ever go down in high weeds, just flip the switch to activate a constant "SOS" tone for easy recovery!
Partsbaba Quality Commitment: All ReadytoSky components are 100% genuine and original. We offer a 14-day replacement warranty against manufacturing defects, so you can fly with the confidence that you'll always find your way home.
