Rotorflight is a Flight Control software suite designed for single-rotor helicopters. It consists of:
- Rotorflight Flight Controller Firmware
- Rotorflight Configurator, for flashing and configuring the flight controller (this repository)
- Rotorflight Blackbox Explorer, for analyzing blackbox flight logs
- Rotorflight LUA Scripts, for configuring the flight controller using a transmitter
Built on Betaflight 4.3, Rotorflight incorporates numerous advanced features specifically tailored for helicopters. It's important to note that Rotorflight does not support multi-rotor crafts or airplanes; it's exclusively designed for RC helicopters.
This version of Rotorflight is also known as Rotorflight 2 or RF2.
Tutorials, documentation, and flight videos can be found on the Rotorflight website.
Please download the latest version from github.
Rotorflight has many features:
- Many receiver protocols: CRSF, S.BUS, F.Port, DSM, IBUS, XBUS, EXBUS, GHOST, CPPM
- Support for various telemetry protocols: CSRF, S.Port, HoTT, etc.
- ESC telemetry protocols: BLHeli32, Hobbywing, Scorpion, Kontronik, OMP Hobby, ZTW, APD, YGE
- Advanced PID control tuned for helicopters
- Stabilisation modes (6D)
- Rotor speed governor
- Motorised tail support with Tail Torque Assist (TTA, also known as TALY)
- Remote configuration and tuning with the transmitter
- With knobs / switches assigned to functions
- With LUA scripts on EdgeTX, OpenTX and Ethos
- Extra servo/motor outputs for AUX functions
- Fully customisable servo/motor mixer
- Sensors for battery voltage, current, BEC, etc.
- Advanced gyro filtering
- Dynamic RPM based notch filters

- Dynamic LPF
- High-speed Blackbox logging
Plus lots of features inherited from Betaflight:
- Configuration profiles for changing various tuning parameters
- Rates profiles for changing the stick feel and agility
- Multiple ESC protocols: PWM, DSHOT, Multishot, etc.
- Configurable buzzer sounds
- Multi-color RGB LEDs
- GPS support
And many more...
Rotorflight Configurator requires Windows 10 or later. Windows 7 is not supported.
Windows has sometimes issues with detecting the flight controller USB device correctly. Impulse RC has created a Driver Fixer software for fixing these issues. You can download it here.
In most Linux distributions your user won't have access to serial interfaces by default. To add this access right type the following command in a terminal, then log out and log in again:
sudo usermod -aG dialout ${USER}
If you experience graphics display problems or smudged/dithered fonts display issues in Rotorflight Configurator, try invoking the rotorflight-configurator
executable file with the --disable-gpu
command line switch. This will switch off hardware graphics acceleration. Likewise, setting your graphics card antialiasing option to OFF (e.g. FXAA parameter on NVidia graphics cards) might be a remedy as well.

Rotorflight is software that is open source and is available free of charge without warranty.
Rotorflight is forked from Betaflight, which in turn is forked from Cleanflight. Rotorflight borrows ideas and code also from HeliFlight3D, another Betaflight fork for helicopters.
