Butterflight Configurator is a crossplatform configuration tool for the Butterflight flight control system.
It runs as an app within Google Chrome and allows you to configure the Butterflight software running on any supported Butterflight target.
There is also now a standalone version available, since Google Chrome Apps are getting deprecated on platforms that aren't Chrome OS. Downloads are available in Releases.
Various types of aircraft are supported by the tool and by Butterflight, e.g. quadcopters, hexacopters, octocopters and fixed-wing aircraft.
This configurator is the only configurator with support for Butterflight specific features. It will likely require that you run the latest firmware on the flight controller. If you are experiencing any problems please make sure you are running the latest firmware version.
Download the installer from Releases.
