Lost Model Tracking Alarm Buzzer for RC Receivers

Compact lost-model alarm that plugs into your RC receiver and sounds a buzzer to lead you to a downed aircraft in long grass, crops or scrub. It works with AM/FM PPM and FM/PCM receiver systems.

Key features

• Loud 83-86 dB buzzer to follow by ear to the crash site

• Powered by the receiver, so there is nothing extra to charge before a flying session

• Stays silent until it is connected to a receiver, avoiding false alarms in your field bag

• Standby draw under 1 mA barely touches the flight battery

• Small 17.2 x 22.8 mm body tucks inside a fuselage or onto a frame arm

Specifications

• Operating voltage: 3-5.5 V

• Standby current: under 1 mA

• Max working current: 72 mA

• Sound level: 83-86 dB

• Size: 17.2 x 22.8 mm

• Compatibility: AM/FM PPM and FM/PCM systems

It suits models whose receiver drives servos or ESCs directly through PWM channel outputs, such as fixed-wing planes and basic multirotor builds. On FPV quads with a serial-only receiver, use the flight controller's buzzer output or a self-powered beeper instead.
