Overview

The SPM4651T DSMX SRXL2 Serial Micro Receiver takes the original SPM4649T receiver and adds more value, functionality, longer control and telemetry link range. The SPM4651T uses our feature-rich SRXL2 protocol to give pilots a blazing fast serial data connection with up to 20 channels. SRXL2 is a powerful and open source communication protocol developed by Spektrum. It greatly improves bi-directional communication between the radio system and flight controller for added telemetry functionality and flight control configuration right from the pilots Spektrum Transmitter*, all over one signal wire.

The SPM4651T is small, lightweight, and ideal for Heli, Multi-Rotor and FPV Enthusiasts. It also features a simple bind button so pilots no longer need to carry a separate receiver or bind plug to bind. Dual antennas provide receiver diversity for solid signal and the long coax antennas help to provide maximum signal strength in all orientations for challenging installations where carbon fiber, metal and batteries shield the antenna. And with Spektrum DSMX 2.4GHz RF protocol the Spektrum SRXL2 Serial Telemetry Receiver provides remarkable range and interference free performance.

FAQ

That is typically ok as modern DSMX receivers are very reliable, however the ideal placement would be to have the antennas perpendicular. One running horizontally down the fuse and the other placed/taped vertically in the fuse.

Placing the antenna perpendicular will provide the best signal reception.

It comes with a 4-wire SRXL2 lead only, it will not function if connected to a 3-pin socket.

Both the SPM4651T and SPM9747 are compatible with the AR8360T. I don't see a reference to the SPM4751T in the online manual (these are the most recent), but yes that would be a misprint.

The SPM4651T would work well as a remote receiver with the AR637T. The SPM4649T is no longer available.
