Jeti USA Duplex EX R7 REX 2.4GHz Receiver with Telemetry & Stabilization

Download the Instruction Manual Here


The REX Assist receivers enhance the REX series of receivers and extend it with the intelligent flight stabilization feature, which is designed for airplane models and multicopters. This stabilization works in all three axes of the model and facilitates flying in windy or otherwise challenging conditions. Aerobatic maneuvers will be more accurate and smoother. With the help of several flight modes, which are also suitable for beginner pilots, flying practice will be really easy.

  • Up to 16 Stabilized Individual Channels
  • Different Multicopter Types, from Tricopters to Octocopters
  • Up to 3 Adjustable Flight Modes, Options for Stabilizing the Horizon and Altitude
  • In-flight Gyro Gain Tuning Using Available Channels
  • Latest 3-axis Gyroscope, 3-Axis Accelerometer and Barometric Altimeter
  • Support for External Ultrasonic Altimeter
  • Support for LED Light Strip, and External Camera Gimbal
  • Intelligent Fail-safe, and Vibration Analysis
  • Wireless Transmitter programming and PC Support
  • Available Telemetry: Rx Voltage, Signal Quality/Strength, G-Force, Attitude Orientation

The Duplex system is a revolutionary digital 2.4GHz frequency hopping radio system that is designed and manufactured by Jeti Models in the Czech Republic. The REX and REX Assist Jeti Duplex 2.4GHz Receiver lines include many built-in features like:

  • Internal Data Telemetry Logging (Black Box)
  • Integrated Multi (3) Input/Output Telemetry & EX Bus Expander
  • 32 Bit Microprocessors (No limits for Future Firmware Upgrades)
  • Wirelessly programmable failsafe
  • Integrated digital telemetry (Rx Voltage, Signal Quality)

The Jeti REX line of programmable receivers was developed to take full advantage of multi-port (Ext, E1, E2), multi communication protocol (EX Bus, UDI 12/16, PPM) configuration and fully implement Duplex EX Bus (Device Manager) or third party devices that use EX Bus for telemetry and programming integration.

One of the most attractive features of the Duplex 2.4GHz line of products is the full integration with all Duplex telemetry sensors. You can easily observe up to 40 different parameters in real-time directly on the transmitter. Or, by using the JetiBox Profi (sold separately) you can see your data in parallel mode giving you and your copilot valuable real time information.

Airplane Menu
The Airplane Settings Menu allows you to adjust gain and stick priority for all three axis directly from the transmitter. It also allows you to control stick priority which reduces gain at the extreme ends of travel by the amount that is entered.

Stabilization Menu
In the Stabilization Settings Menu, you assign the three flight modes and make adjustments, individually, for all three including the damping mode, default gain and which channels are stabilized.

Advance Properties
In the Advanced Properties Menu, you control the general settings like the output period, number of PPM channels, and whether or not to stabilize the EX Bus output. It is also here where you adjust the PID settings for the three axis.
