JR RG631B 6-Channel Full Range 2.4GHz DMSS Receiver with telemetry. The RG631B is designed for full range flight featuring telemetry, a coaxial antenna and a remote antenna to ensure a rock solid signal in any orientation.

Dual Modulation Spectrum System (DMSS)* 2.4GHz protocol offers a secure radio link that combines DSSS and FHSS capabilities into a wideband transmission system and includes high-speed response and high resistance against RF noise. One benefit of DMSS is the JR® Intelligent Output System (IOS), which automatically selects control signals that need to be transmitted at exactly the same time 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 when operating a wing control surface with multiple servos.

Another feature of DMSS is its bi-directional communication that supplies telemetry information. Receiver voltage telemetry is built in as standard in every DMSS receiver, and add-on sensors will give you real time feedback of information from your model, such as the RPM of an aircraft propeller or helicopter rotor blades, temperature and variometer/altimeter readings.

Key Features:
• Designed for full range flight in any size model
• Remote antenna included
• High speed response and high resistance against RF noise
• Bi-directional communication supplying telemetry information
