doc.rotorflight.orgWeb Configurator
Connect, flash and configure your flight controller straight from the browser. No install needed, with desktop builds also available.
cfg.rotorflight.orgBlackbox Explorer
Analyse flight logs frame by frame, sync them with video, and dig into gyro, PID, governor and RC data after every flight.
blackbox.rotorflight.orgRadio & Lua Suites
Configure, tune and monitor telemetry from your transmitter with the Rotorflight Lua suites for FrSky Ethos and EdgeTX.
Radio guidesSupported Hardware
Flight controllers, receivers and ESCs that work with Rotorflight, plus wiring guides and reference designs for manufacturers.

Start tuningRotorflight 2.3
The newest official release brings Rotorflight Rates, a reworked nitro governor, battery profiles and a long list of new hardware and protocol support. Read the release notes, back up your configuration, then update with the configurator.
New to Rotorflight? The getting started guide walks through flashing, first connection and setting up your helicopter step by step.
Why Rotorflight?
Flight control designed from the ground up for helicopters, not adapted from multirotors
Governor
A headspeed governor with precompensation for collective, cyclic and yaw, for electric and nitro helicopters alike.
Advanced Filtering
Identify vibration with Blackbox and remove it with RPM-based and dynamic notch filters for a locked-in feel.
Tune From Your Transmitter
Use the Lua suites or adjustment functions to change settings at the field, without a laptop.
Rescue Mode
One switch flips the helicopter upright, levels it and climbs away to get you out of trouble.
Motorised Tail
Full support for motorised tails, with Tail Torque Assist (TTA) to keep the tail holding under hard load.
ESC Telemetry
Read RPM, voltage, current and temperature from a wide range of ESCs and pass it straight to your radio.
About Rotorflight
Rotorflight is a flight control software suite for single-rotor RC helicopters. It began as a fork of Betaflight, and has since been reworked throughout for helicopters: a swashplate mixer, governor, tail control, rescue and filtering are built around how a rotor head actually flies.
The project is developed in the open by a team of pilots and engineers. The firmware, configurator, Blackbox Explorer and transmitter Lua suites are all free, run on a wide choice of off-the-shelf flight controllers, and keep improving with every release thanks to community feedback and contributions.
For 3D & Sport
Crisp, consistent response with a stable headspeed for hard 3D and smooth sport flying.
For Nitro & Gas
A governor tuned for I.C. engines, with throttle handling built for nitro and gasser machines.
For Scale
Calm, predictable control for large scale helicopters and a motorised tail option.
