Overview
R9 STAB OTA is a 900MHz long-range and stabilization receiver with a built-in 3-axis gyroscope and 3-axis accelerometer.
MULTIPLE FLIGHT MODES
R9 STAB OTA has 8 PWM channels, on traditional fixed-wing models it will support stabilization, automatic level, hover and knife-edge flight modes. For delta wings and V-tail models, it supports stabilization and automatic level flight modes.
ACCESS PROTOCOL
R9 STAB OTA receiver implements the ACCESS protocol and brings the user improved performance and features. It supports wireless over-the-air firmware updates, making binding to receivers even easier as well as conveniently checking the current receiver firmware version.
CONFIGURATION PARAMETERS
Paired with a FrSky radio transmitter, the parameters can be adjusted conveniently through the LUA script. In addition, parameters may also be adjusted by FreeLink (PC) and FreeLink App (with AirLink S).
