RXD3 is a professional receiver ultra long range up to 200Km with temetry and optional Mavlink radiomodem.

The most powerful receiver and of greater range that will provide you with distant flights EVLOS with the security of a good radio link.

Manufactured with the latest technology of 5th generation of long range DMD radios.

Compatible with XPAD3 transmitter 


Two RXD3 receivers can be connected to provide of a redundant system in the same band or in different bands. (Consult).


Note: In the XLRS_D3 system the configuration of the mixtures, button activation and encoder assignment are performed on receivers and not on transmitter (XPAD3), as usual in RC systems form amateurs.
EVLOS: Extended Visual Line Of Sight operations


Professional Radio Control and Telemetry with extraordinary range in ISM free band. Up to 200Km maximum for XLRS_D3 systems. There are different options of the same system with scaling of ranges and prices to adapt to your budget.

-116dBm maximum sensitivity.

1000mW of maximum RF power.

Mixtures in the receiver

New concep in controls, Mixtures and RC model parameters in the receiver and not in the XPAD transmitter.

Advanced MIXER: 8 mixes of 3 inputs, variables and offset.





Internal Radiomodem with internal MAVLINK protocol optional. Compatible with autopilots: APM, Pixhawk, PX4…

Serial TTL port (0 to 3,3V) configurable from 9600 to 115200b for modem.

Configurable with DMDStudio

Configuration software, upgrade and utilities for all DMD productos, used ALPHA command language of DMD.





AES encryption

Advanced Encryption Standard (AES) is a standard method used in cryptography.

The RXD3 receiver uses AES encryption and supports keys of 16bytes or 128bits.



Servos Outputs

8 multifunction outputs for RC servos.

Servo output CH7 SPPM series for direct autopilot connection, configurable and assignable to any number of servo, joystick, encoder, switch, buttons or to any mixture. Electronic limitation servos, TRIM, SUBTRIM, REVERSE, etc.

Control of 16 servos and assignment Joysticks and RC channel EPOS output.

USB, RCBus, i2c

The USB facilitates the update of programs and the tests and direct configuration from PC to the receiver and all the devices connected in network by RCBus.

Direct connection to XOSD or to other XLRS devices by RCBus. Two RCBus interfaces compatible with ACL commands.

And i2C interface is used to connect various future devices such as OLED display for the aircraft, additional sensors, IMU, etc.


OSD for the XLRS system with 2.4Ghz video transmitter of 500mW. It is connected to the RXD receivers by RCBUS. Two video inputs for cameras. Thermostat to cool with fan.
