Reedy electronic power switch
Reedy’s new electronic power switch is a reliable and versatile alternative for 1:8 racers fed up with failure-prone mechanical switches. The LiPo mode option prevents over-discharging your receiver battery, while on-board LEDs serve as a battery capacity indicator displaying real-time state of charge. The lightweight and compact design mounts with double-sided tape or use the included transponder mounting bracket, depending on your desired configuration.
