Advanced configuration
Core flight behavior, radio, audio, OTA, and device files.
Tone Studio (browser preview)
Plays a short preview using selected tone profile and envelope settings.
--
Tip: update tone settings first, then preview the result.
Firmware update (BLE OTA)
Checks this site for the latest firmware and flashes it over BLE.
