This is an ImmersionRC EzUHF 4 Channel Receiver. The smallest receiver in the EzUHF family, this receiver features four Servo Outputs, with 12 channel PPM capability. It delivers the same sensitivity as it’s 8 channel big-brothers, in a significantly more compact case.
A Full Featured Long Range System
When 2.4GHz R/C systems run out of steam, UHF Long Range Systems (LRS) are ready for more. The EzUHF system has proven performance, and is a top choice among long-range FPV experts.
Built-in Spectrum Analyzer
The only commercial LRS to include this essential feature; a built-in Spectrum Analyzer. This essential tool may be used to ensure that a model emits no interfering emissions on the UHF band, which could reduce range. Plug in a standard USB cable, install the free ImmersionRC Tools, and create charts of power emitted on the UHF spectrum.
Arbitary Channel Mapping
Using the ImmersionRC Tools, the servo outputs of the EzUHF 4 channel receiver may be arbitrarily remapped to suit the target model. Multicopter wiring may be greatly simplified using a single PPM cable, and easily configured using the tools. Need PWM outputs to drive Pan/Tilt servos? No problem using these tools.
Uplink Status (UPSTAT)
All uplink status is available in the single-cable PPM stream for use by supported OSDs. The XuGong v2/Pro, or XuGong Vortex both take advantage of this method to show critical uplink status on-screen. The received signal strength (RSSI) of the receiver’s antenna, along with the link quality, are captured by the OSD, and displayed with appropriate alarms to indicate marginal conditions. NOTE:
EzUHF Firmware v1.51 or later required to support single-cable UPSTAT.
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).
