New concept 


The operation of the XLRS systems is noticeably different and better than the standard RC (Radio Control) Transmitter-receiver systems.


The XLRS system is more agile and versatile, it allows to realize configurations and functionalities that can’t be done or imagined with other normal RC systems.


  • Data transmission (RAW).
  • Mixtures and parameters of the model in the receiver, not in the standard RC transmitter.
  • More RC Channels.
  • Different concept of RC channel and many more possibilities.


In this link you will find more detailed information  on the concepts of receiver operation, joysticks and mixtures.





The difference of a standard RC system that sends 10 or 12 RC channels, the XLRS sends the digital values of Joysticks, encoders, buttons, switches and pushbuttons. 

The data is sent flat (RAW), means without mixtures.

The configuration of the UAV or drone is in the receiver and not in the RC transmitter.


With this way of working there are numerous advantages:

You can use different XPAD transmitters with a single drone or UAV without having to configure anything.

There may be several pilots in the distance and “pass” flight control from one to another instantly.

For this you only have to deactivate the transmitter with the hot keys, even piloting another you can continue to receive telemetry in your XPAD.

You can also fly many drones or UAV configured differently with a single station. Combining this with the list of authorized equipment (LEA), you can pilot or several fleets of up to 255 drones or 16 specific UAVs with exact IP..



The possibilities are awesome!!!





Mixtures and parameters of the model in the receiver, not in the standard RC transmitter.

Multiple advantages in professional systems.

There is no need to change the model in the RC Transmitter.

More security, fewer errors by not having to change the RC model in the transmitter when several models are used.

In the configuration of the devices, you can use an RF IP subnet or include the authorized receivers in the LEA (Authorized Equipment List).

When sending data without mixing and the mixtures are in each RC model locally, you can command several models
although they are very different.

Each mix has 3 inputs assignable to any Joystick, encoder, button or other mix output.





There aren’t 8 or 12 channels, if not many more. The concept of RC channels changes.

Although the concept is different, to compare 13 channels can be used in the SPPM output (which normally connects to the autopilot), more 1 for each servo output in each device (receiver, osd, etc).

In summary, 24 servos or more can be connected, it depends on the dispositives in the RC model.

The mixtures are independent in each receiver and in the XOSD.

Each physical servo output it can be assigned to a Joystick, a button, an encoder or a mix.

Servos MIX.





On traditional RC Transmitters, a channel corresponds to a function (Ailerons, Motor, etc.) and has a single servo output.

In XLRS systems, every element of the RC transmitter (we will call them objects from now) as a joystick axis, a button, an encoder, etc., can be assigned to one or more servos or mix or mix input in the receiver or in any device XLRS (another RXD, XOSD, etc) that has output of servos.

Of course it can be configured in part as a traditional RC transmitter or use the new functions.

Each device in flight (receiver, OSD, etc.), has its own mixes and assignments of objects to its servo outputs.

36 basic objects: 18 main pilot and 18 auxiliary copilot/observer.

More possibilities.
