JR has broken the mould with this interesting new 11X Zero 2.4GHz radio system. Love or hate the new styling, the design is said to be heavily influenced by Japanese ‘Gundam’ model robots.
JR’s UK distributor, MacGregor Industries expects to have the 11X Zero transmitter available very soon, once CE type testing has been completed. The 11X Zero transmitter has eleven channels, a 30 model memory and a SD card slot. The usual three-model type selection is available for Helicopter, Airplane and Glider.
It is compatible with all DSM2 receivers and will be supplied with either an RD921 or RD1221 receiver as a combo. Each combo will include 1500mAh Tx and Rx packs, a charger, a bind plug and a manual.

The last 11X software upgrade is 0002-0103. This version can be down loaded from the JR Americas web site. The version two software programming is similar to that used on the earlier version of the XG11. How to find the SD Card slot on the JR 11X transmitter and save model memory to it. All the great programming features of the JR® XG11 transmitter are now available to owners of the 11X transmitter via a software update. In this video, John.
When a SD card (not supplied) is fitted it can be used to store model set-up data and also to upgrade the 11X with data downloaded from a PC. A three colour LED under the aerial declares the operating status of the transmitter. Green shows that the Tx is in stand-by mode. Blue indicates that RF is on, while Red shows that RF is off.
Programming will be familiar to current JR users using a combination of a rotary selector and four buttons alongside the back lit display. Modellers upgrading from a different manufacturer will find it a very easy radio to set-up.

EzUHF firmware v1.53 adds more customisation possibilities to lower the latency throughout all the transmission chain using several techniques:
- serial input to the Rx JR module from the remote
- SBus output from the receiver
- customisable number of transmitted channel
- synchronisation of the whole transmission chain
It still supports the well tested PPM behaviour and PPM input and output and these can be used in combination with the above settings.
As the setup has more options, it gets a bit more complex to setup so that the transmitter and receiver can talk to each other.
Here is a guide to get the system set up.
Transmitter Setup
Loading the firmware
Depending on the remote and transmitter, you can load one of these firmwares, following the update procedure as described in the manual:
- standard firmware using PPM
- race firmware, using the DSMX/DSM2 output from the Taranis, for the JR module.
Configure the connection from the remote
Setup your Transmitter to emit:
- PPM like described in the manual for PPM firmware
- DSM2/DSMX output for race firmware. For the Taranis, this currently only supports six channels output.
Check the connection to the remote. In low power mode, turn on the remote.
It beeps some welcome beeps at startup: 3 times for PPM firmware, 4 times for Race firmware. After a short pause, it beeps once if it recognises the signal from the remote.
Configuring the transmission mode
Once the Tx is configured to receive signal from the remote, it can be configured through USB. Note that it needs to be plugged in the remote and the remote powered to respond on USB.
You can set one of the default setup Race or Standard with the button in the main configuration tab. Or you can configure how the controller data is sent over the air in the EzUHF Advanced tab, on the right side of the pane configuring the Tx: Download commbank app for android.
- number of channels transmitted “RF Channel Count”: less channels means shorter transmission time and less chance of transmission error. Configure the number of control channels you need.
- Transmission mode: either the standard or race mode. Race mode transmit data synchronously with the remote output, to minimise latency.
The number of channel must match between transmitter and receiver for them to recognise each other.
Receiver Setup
Jr 11x Manual
Loading the firmware
The receiver can output control in different formats depending on the firmware:
- PWM and PPM on multiple servo outputs with the standard firmware
- SBUS output on servo output 1 for flight controllers supporting SBUS inputs
Configuring the receiver
Set one of the default setup with the buttons on the main page, or set the details in the EzUHF Advanced tab:
- number of transmitted channels “RF Channel Count”: corresponding to what you set for the transmitter.
- number of emitted channels “PPM Channel Count” (for PPM, SBUS is always the same 12 channels). This allows to emit more channels than transmitted, to add UPSTAT, RSSI and Link Quality channels.
- transmission mode: use race mode to synchronise to packet reception for lower latency.
NOTE: transmission race mode outputs data when it receives it from the TX, if nothing is received, it stops transmitting. This mode has NO FAILSAFE, so you should use the failsafe of the flight controller.
Binding
Bind the TX to the RX as usual, following the procedure described in the manual.
Servo values
Jr 11x Update
If using race mode, check the center and extremes of the PPM values, for example using CleanFlight configurator Receiver tab, to ensure the minimum/center/maximum values match 1000/1500/2000.

For combinations of PPM and SBUS firmwares, you’ll need to lower the endpoints, as they don’t use the same definition of stick values to output values.
