First flight of my head tracked DJI FPV Avanti EDF jet with our own pan/tilt and the 2" RCGauges realtime telemetry display. Predictably not great in bright sunlight in an open cockpit but subsequent to this video cloudy day and late afternoon/evening flights have been a lot better in terms of visibility of the 2" display.
