Frequently Asked Questions

What is the operating voltage range for the R9 STAB OTA receiver?

The R9 STAB OTA receiver operates on a wide DC voltage range from 3.5V to 10V. This allows it to be powered directly from a 1S LiPo, a regulated 5V BEC, or typical 2S-3S LiPo battery inputs through a suitable voltage regulator, providing great flexibility for various aircraft power systems.

Which transmitters and modules is this receiver compatible with?

This receiver is compatible with FrSky transmitters equipped with the R9M Lite, R9M, or R9M 2019 modules running ACCST firmware. For full ACCESS protocol features like OTA updates, the transmitter and module must also be updated to support the ACCESS protocol.

What flight stabilization modes does the built-in gyro support?

The integrated 3-axis gyro and accelerometer support stabilization and automatic level flight modes for all model types. For traditional fixed-wing models, it additionally supports hover and knife-edge flight modes. Configuration is achieved via transmitter LUA scripts or the FreeLink PC software.

How do I update the firmware on the R9 STAB OTA receiver?

The receiver supports Over-The-Air (OTA) firmware updates via a compatible FrSky ACCESS transmitter. This process is performed wirelessly through the transmitter's interface, eliminating the need for physical USB connections and simplifying the update procedure in installed aircraft.
