Overview
The SPM4650 DSMX SRXL2 Serial Micro Receiver takes the initial SPM4648 receiver and adds more value, performance and fly-by telemetry, while reducing the size and weight of the currently micro sized Spektrum serial receiver. The SPM4650 uses our feature-rich SRXL2 procedure to offer pilots a blazing quickly serial data connection with up to 20 channels. SRXL2 is a powerful interaction procedure that enhances bi-directional interaction in between the radio system and flight controller for added telemetry performance and flight control configuration right from the pilots Spektrum Transmitter*, all over one signal wire.
The SPM4650 is little, light-weight, and customizable, providing an outstanding receiver for even the tiniest of applications. It also features a basic bind button so pilots no longer require to carry a different receiver or bind plug to bind. Dual antennas supply receiver diversity for strong signal and the long coax antennas assist to supply maximum signal strength in all orientations for challenging installations where carbon fiber, metal and batteries protect the antenna. And with Spektrum DSMX 2.4GHz RF procedure the Spektrum SRXL2 Serial Micro Receiver provides impressive range and disturbance complimentary performance.

Fly-By Telemetry

Fly-By Telemetry
Fly-By Telemetry is a low range telemetry signal that is perfect for examining telemetry prior to and after a flight. And with SRXL2 Innovation users will get even more telemetry data and transmitter to device shows assistance by means of Forward Programming, VTX Setup, and/or Text Gen Programming.
 





Dual Variety Antennas
The SPM4650 utilizes an advanced antenna diversity system that provides ideal range, RF performance, and polarization. All supported by 2 long coaxial antennas that are perfect for FPV, Multirotor and Heli pilots with metal and carbon fiber abundant models.
 

Bind Button installed for Easy Binding
No bind plug? No Problem! The SPM4650 is the most convenient to bind Spektrum serial receiver yet, merely press the bind button at any time, prior to or after power is applied, and the SPM4650 is in bind mode.
