Betaflight

Betaflight is an open-source flight control software for FPV drones, chosen by the FPV drone racing and freestyle community for its performance and features. It provides an On Screen Display (OSD) to overlay flight metrics onto the FPV video feed and supports a wide range of flight controllers.

Betaflight is a flight control software for multi-rotor and fixed-wing craft, primarily used in FPV drone racing. It offers an On Screen Display (OSD) feature that allows users to overlay key flight metrics like battery, speed, and altitude onto their FPV video feed, which aligns with the 'Live FPV Video Feed' and 'AR Heads-Up Display' features. The OSD also provides 'battery metrics, speed, altitude and home direction' which can be considered a form of 'Telemetry Dashboard'. The 'drag-and-drop' functionality for setting up OSD elements suggests a 'Customizable HUD'. However, it does not explicitly mention features like virtual power-ups, lap tracking, or interactive track maps, which are core to the Mario Kart-style experience of KartVision AR.
