Based on the proven RG712BX Receiver, JR's new RG812BX not only features an additional 8th channel, but a unique "hybrid port" that allows the Aux 3 servo ports to be used either as conventional PWM servo ports, or as a direct XBus serial connection. 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 RA02TL 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 JR's 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 JR's 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.

Not only does this receiver listen, but it talks back as well. DMSS is a bi-directional communication system that delivers real-time telemetry information. Receiver voltage telemetry is standard with every DMSS receiver, and add-on sensors are available to monitor nearly every metric vital to the operation of your mode.

The firmware in a 2k servo verifies the position of the servo arm two thousand times each second,
while the firmware found in previous servos verify the arm’s position one thousand times per second.
This greater number of verifications makes for a very precise servo, and gives it a more “solid” feel.

It is recommended to use a booster cable with 2k servos to ensure steady voltage at all times.
