The JR 11X 2.4 comes with just about everything you would expect in a pro-class radio. Things like an extensive list of programming options, 30-model memory, a big backlit display and a eye-catching case worthy of its capabilities. The only thing it lacks is the one thing you won’t miss - a pro-class price tag.

The 11X is also surprisingly easy to use for a radio so advanced. Accessing functions and programming settings is simple with the intuitive roller button interface and big, backlit LCD screen. It also has an SD card slot for model storage, memory expansion and software updates.

Most importantly, it comes equipped with the security and convenience of Spektrum 2.4GHz DSM technology. With DSM you get more than the best 2.4 radio control technology flying. You also get more receiver choices designed for specific types of flying as well as access to the exciting world of Bind-N-Fly® aircraft.

Technical Notes

                          Updating the 11X Firmware via SD Card

Read all firmware instructions thoroughly prior to updating your SD card. If you are not comfortable updating your 11X, contact Horizon Hobby Product Support at 877-504-0233 for assistance. Although model memory should not be lost during this process, it is always a good practice to back up your models prior to performing this update.

WARNING: The 11X software update located here is only compatible with the JR 11X radio distributed through Horizon Hobby Inc. Do not attempt to install this software in the 11X Zero sold through JR Propo and their other distributors. Doing so may cause a non-recoverable software error that will require a costly repair.

Before performing updates to your 11X, you must create the necessary folder and sub-folder on your SD to store the firmware update. You can do this using any computer that has an SD drive. JR recommends using SD cards with a minimum of 1 GB or higher capacity, which you can purchase through any computer hardware provider or retail outlet.

With your computer, create a folder on the SD Card titled JR, and then create a subfolder titled VERUP in the JR folder. Any JR Firmware updates will be titled XXXX.JRD. Copy the updated file(s) (XXXX.JRD) file to the VERUP subfolder.

WARNING: When performing 11X firmware updates, DO NOT disconnect the battery while the update is in process. Doing so will create a non-recoverable corruption of the 11X firmware requiring you to send in your transmitter for service.

Prior to updating your firmware, ensure the battery has a minimum of 10.0V. If you have changed the default low battery warning, the battery voltage will need to be a minimum of 1V above the warning threshold.
Instructions for the update:

•  Open the battery door and remove the battery. Leave it plugged in. You will then have access to the SD card reader located on the green circuit board on the right side of the battery compartment.

•  Vertically insert the SD Card into the reader.

•  Replace battery and door to prevent the battery from becoming disconnected during the update. (see Warning above)

•  Hold down the bottom left button of the transmitter and turn on the unit. A Green LED will light at the top of the transmitter and you will be taken to the update screen. The display will show you both your current software version and the new version on the SD card. (For example V0100-0100 to V0100-0101).

•  Press UPDATE to install the update. You will be prompted to turn off the transmitter to begin the update. If the battery voltage is below 10 volts or less than 1 volt above cutoff, the update will be interrupted with a “lowbatteryerror” message. If you receive this error, you will need to charge your transmitter or change the low voltage cutoff in the transmitter settings.

•  Next, turn off the transmitter. The screen will display “update in progress”. Do not disconnect the battery. The green LED and screen will remain on during the update. When the update is complete (one to two minutes on average), the screen and the LED will turn off.

•  Turn on your transmitter and check the version of software on the TX SETTINGS screen in the system menu.
