JR RG812BX-B DMSS Extended Rx (9-16 Ch)


The new RG812BX-B Extended 9-16 channel receiver is based on the previous RG812BX, but is intended to extend channels from the standard 8 up to 16, while offering a redundancy system at the same time!

Simply bind a standard RG812BX receiver AND the new RG812BX-B receiver to your model, activate XBus in mode A in your system and have up to 16 Standard PWM channel access total, with dual receiver redundancy, all without the expense and complexity of additional hubs and servo harnesses.

The RG812BX-B 9-16 Extended channel receiver is designed for use ONLY with an additional RG812BX as it does not offer telemetry due to its role as a secondary, redundant, channel expanding receiver.

So, if you are looking for a robust, simple solution to expand your channel availability, while adding system redundancy, the RG812BX-B 9-16 Extended Channel DMSS receiver is an excellent choice!

Featuring path diversity antennas for outstanding signal reception, and increased telemetry signal syncing. With path diversity antennas, a remote antenna is not required, but an RA03TL remote may be added to the RG812BX for additional antenna diversity, further enhancing signal reception. The RG812BX allows you to simplify your antenna setup, have the security of full range operation, while still enjoying the benefits of built-in telemetry and XBus functionality.

The RG812BX utilises JRs robust DMSS modulation system that combines attribute from both DSSS and FHSS modulation into a wide-band transmission system with high-speed response and high resistance to RF noise. Also unique to DMSS is JRs Intelligent Output System (IOS), which automatically selects control signals that need to be transmitted simultaneously and delivers the data as one complete signal frame. IOS ensures there is no time delay when commanding servos used for critical functions such as a CCPM swashplate on a helicopter or with an aircraft with multiple servos ganged on a single control surface. This gives a stronger connection in flight and can reduce wear on components, keeping your model flying better, longer.


  • Path diversity antennas provide full-range signal and telemetry data without a remote antenna.
  • 5-channel standard PWM output and single shared XBus or PWM output can be used parallel with one another for additional capability.
