EzUHF Transmitter – JR Module

The modular form of the EzUHF Transmitter, plug and play with several popular R/C transmitters.

A Full Featured LRS

When 2.4GHz R/C systems run out of steam, UHF Long Range Systems are ready for more.

The EzUHF system has proven performance, and was used by the long-range FPV experts for their famous proximity flights.

  • Standard JR module format, compatible with Taranis, 9XR/9XR Pro

  • 500mW of clean RF output power, with a low-power mode switch

  • Built-in headtracker port, capable of powering a headset

  • 100% compatible with all EzUHF receivers

  • USB port for future upgrades


A Family of Receivers

The EzUHF family includes three receivers, ranging from the top of the line 8 Channel Diversity to the lightweight 4/12 Channel model.

The diversity model includes twin antenna inputs for those who wish to push the limits. Two antennas angled from each other ensure that polarization mismatches, or nulls due to multi-pathing, are not an issue while barreling down a mountain pass.

The 4/12 channel model, recently equipped with a tough plastic case, is ideal for use in multi-copters, where all 12 channels are sent down a single PPM cable.


Headtracker Support

The EzUHF transmitters include the best headtracker support in the hobby.

A dedicated port on the transmitter (both JR, and cased versions) provides power to a headtracker-equipped headset, and accepts a PPM stream including pan, tilt, and also roll channels.
These channels may be arbitrarily mixed into the RF uplink.

Couple with FatShark’s state-of-the-art ‘Trinity’ headtracker module for a superb FPV experience. A 9 degree of freedom (3 axis of Gyro, 3 of Accelerometer, and 3 of Magnetometer) IMU ensures zero drift, and a natural headtracking experience.


On-Screen Uplink Status

The EzUHF system includes a simple way to show uplink ‘health’ on-screen, so that it is always visible during a flight. Using either the i2c link of the 8 channel diversity or 8 channel lite receivers, or the new ‘UPSTAT’ feature of all UHF receivers, the OSD shows the uplink status.

Received Signal Strength of each antenna is shown, along with the link quality, and the dropout count. All of these are critical when it comes to pushing the limits.

Uplink status is also included in the OSD’s telemetry downlink, and may be recorded along with the video.


Simple Failsafe

Setting the failsafe on the EzUHF is as simple as pressing a button on the back of the transmitter during flight.

Set your model into a gentle turn, drop the throttle, and set the failsafe. In the unlikely situation where the uplink is lost, the model will safely glide to the ground.

On a multicopter, the UHF failsafe will trigger the flight controller’s failsafe, and for most systems will start the RTH (Return to Home).
