RadioMaster Zorro Radio Controller ELRS

The RadioMaster Zorro Radio Controller ELRS is a compact radio transmitter developed for pilots and RC enthusiasts who need precise control in a portable form factor. Its gamepad-inspired ergonomic design provides comfortable handling, while the integrated 2.4GHz ExpressLRS module enables wireless communication with compatible ELRS receivers.

The transmitter features Hall-effect gimbals for accurate stick input and a 128×64 monochrome LCD for accessing model settings, telemetry, and radio configuration. Its EdgeTX and OpenTX compatibility provides extensive customization options, including channel assignments, control mixes, switches, and flight modes.

The Zorro also includes a nano-size external RF module bay, allowing compatible external modules to be installed when additional radio-system options are required. USB-C connectivity supports charging and data communication, making it useful for firmware updates and simulator applications.

How to Use

1. Install two compatible 18350 rechargeable cells, observing the correct polarity.

2. Power on the Zorro transmitter and complete the initial radio setup.

3. Confirm that the transmitter is running compatible EdgeTX firmware and has the appropriate ExpressLRS module firmware.

4. Create or select a model profile for your aircraft or drone.

5. Install a compatible 2.4GHz ExpressLRS receiver in the aircraft.

6. Configure the receiver and transmitter with compatible ExpressLRS firmware settings, including the required binding phrase or binding procedure.

7. Bind the receiver to the transmitter and confirm successful connection.

8. Configure channel mapping, switches, failsafe settings, and control directions.

9. Test all controls and verify failsafe operation before installing propellers or operating the aircraft.

Important Notes

• This is the ELRS version of the Zorro. The CC2500 and 4-in-1 versions use different internal RF hardware and do not provide the same built-in ExpressLRS functionality.

• The built-in ELRS module operates at 2.4GHz. Use a compatible 2.4GHz ExpressLRS receiver.

• RF output power depends on the hardware and regional firmware configuration. FCC and EU LBT versions may have different power limits.

• Two 18350 batteries are required and are not included in the standard package.

• Use compatible rechargeable cells and follow safe battery charging practices.

• Receiver compatibility, available channels, and control range depend on the receiver, firmware, antenna installation, and operating environment.

• External RF modules must match the nano-size module bay and supported electrical interface.

• Always configure and test failsafe settings before flying.

• Keep the antenna properly positioned and avoid operating the transmitter with a damaged antenna.
