Lemon Rx GEN2 7-Channel Stabilizer with DSMX, TEXTGEN Menu, and Voltage Probe

The new Lemon RX Gen 2 TEXTGEN airplane receivers are easier to use. Now, you can do most of the programming right from the screen menu on your transmitter. You can use a Spektrum Transmitter or a Remote Controller with Edge TX, like Radiomaster with 4-1.

What is the Lemon Rx?
The Lemon Rx GEN2 DSMX Compatible 7-Channel Stabilizer is a state-of-the-art receiver designed for remote control airplanes. This device integrates advanced telemetry features, including a built-in barometer, altimeter, energy meter, and internal temperature sensor, providing real-time data to enhance flight performance. Its high-sensitivity gyro, coupled with a proprietary stabilization algorithm, ensures responsive control for both electric and gasoline engines. The innovative TEXTGEN menu allows for intuitive setup via telemetry pages or radio stick movements. Compatible with both the RadioMaster 4-1 radio and Spektrum radios, this stabilizer supports dual aileron operations and includes robust failsafe protection, making it an ideal choice for serious RC hobbyists.

Introducing the TEXTGEN Menu: Revolutionizing Stabilizer Setup

The existing product has been upgraded with the innovative TEXTGEN menu. This feature allows for the setup of the stabilizer without the use of physical buttons. Instead, users can configure settings through the Spektrum telemetry page and by moving the stick on the radio. The stabilizer casing now features a new label design reflecting these changes. However, those who prefer the traditional button method can still use it, as all previous features are retained.

Directions for Using the TEXTGEN Menu

1. Ensure that the first four channels (control sticks) can reach approximately +/- 100%.
2. For Spektrum radios, select the telemetry page that displays Lemon Rx telemetry.
3. For TX16S radios with the latest EdgeTx firmware, a page will show text similar to the example below once the telemetry connection is established upon binding.
4. Within the first 60 seconds after powering on the radio, move the two sticks to the lower left and lower right and hold. "Lm Rx Config" will appear in about 2 seconds. Release the sticks at this point. Use the right stick left/right to navigate the menu (Blue arrow indicates the current active menu). The right stick up/down functions as "Enter" or "Change".
5. Browse through and adjust all settings except enabling failsafe. Ensure to select "Save & Exit" for changes to take effect.
6. Enjoy the convenience and precision of the TEXTGEN menu for all your stabilizer settings!

Reset the Stabilizer

• Connect power to the stabilizer.
• Hold the F and B buttons for approximately 5 seconds until all LEDs flash randomly.
• Press the C button. Multiple LEDs will flash a few times to complete the operation.

Bind with Bind Plug

• Insert the bind plug into Channel 7.
• Connect power to the stabilizer.

Bind without Bind Plug

• Connect power to the stabilizer.
• Hold the B button until the red LED flashes.

Bind with a Satellite without a Bind Plug

• Connect power to the stabilizer.
• Hold the B button until the red LED flashes.
• Disconnect power.
• Plug the satellite wire connector into the stabilizer.
• Connect power again.

Failsafe

• Connect power to the receiver and ensure the servos are working with the transmitter.
• Press the F button for 3 seconds until the green LED changes from off to on and vice versa to change the failsafe setting. The channel value is saved as failsafe default at the time the green LED turns on.
• Turn off the transmitter and wait 2 seconds to ensure the failsafe is activated accordingly by checking for torque generated with finger-pushing the servo linkage if it was set.
