How to Setup an OpenTX Transmitter for Aura

FrSky Taranis X9D+

Jumper T16, RadioMaster TX16S, Multi-Module Transmitters


Yes! FrSky's SBUS works with Aura! And it's the preferred way to to connect and FrSky Receiver to Aura.

FrSky Transmitters are very flexible and configurable. FrSky's implementation of Futaba's SBUS follows the defined SBUS protocol, but the default FrSky Transmitter model settings (such as channel order, travel limits, directions, and centers) differ from a default model settings of a Futaba Transmitter.

Aura Firmware V1.13 and Subsequent Update!

With Aura firmware V1.13 (or newer), Aura now can accept FrSky model defaults via SBus. If you update to V1.13 (or newer), you won't need to download the FrSky Transmitter Model File at the bottom of this page. For tips on updating your Aura, please see our section on Updating Aura Firmware.

Start with a Blank Model and reference the Chart!

Common Transmitter Settings for Aura5, Aura 8 and Aura Professionals starting with a freshly reset transmitter and maintaining normal wing and tail types. NOTES:
1. JR Mode A is preferred as of Aura FW v1.14. For JR Mode B, see the Aura Wiki
2. If you are using a Futaba transmitter, please note that some Futaba transmitters have the throttle set to reversed by default. Leave reversing set to defaults to start, and reverse as needed.
3. Aileron, Elevator, and Rudder should NOT be Reversed, other channels may be reversed at users preference
4. If Flight Modes are set to a channel other than CH5/Gear, set a 3-position switch to that channel and set CH5/Gear as needed.
5. See the Wiki for further details and latest information, and for Hitec use, etc.

FrSky Installation Notes and Equipment Selection

There are three ways to connect the Aura to your FrSky Receiver:

  • FrSky SBUS
  • Traditional PWM Servo Connections
  • FrSky PPM

SBUS is modern digital data on one wire (similar to Spektrum SRXL). It gives the Aura precise knowledge of all of the available channels.

  • Most Preferred and capable FrSky connection
  • Aura will follow the Failsafe outputs of the FrSky Receiver.
  • The SBUS output from the receiver is connected to Aura's B Port (servo bus)
  • Not all FrSky receivers have an SBUS port. A popular choice is the full-range FrSky X4R-SB.
  • The default transmitter conventions of a FrSky Transmitter do not match the default transmitter conventions of a Futaba Transmitter.

Traditional PWM Servo Connection

PWM (Servo Leads) connect the each channel on your Receiver directly to each Servo Port on the Aura.

  • Recommended for all aircraft types.
  • Supports virtually every receiver
  • Limits port availability. Typically Aura will be configured with 4 inputs and 4 outputs with PWM.
  • Some features such as Quick Setup and Quick Trim are NOT supported with PWM connections.
  • All (typically 4) PWM (servo jumper) connections MUST be present to get control of the model which is indicated by a solid green LED (valid radio signal)


PPM (Pulse Position Modulation) all Servo pulses on one wire

  • Works with all aircraft type based on Receiver capability.
  • PPM is input into Aura's B port (servo bus)
  • Since most of these Receivers also offer SBUS, SBUS is preferred over PPM for a clean, accurate digital signal with less latency.
