Air75 Brushless Whoop Frame

The BetaFPV Air75 brushless whoop frame is an ultra-lightweight 75mm micro frame engineered for agile 1S indoor racing and freestyle builds. Moulded from impact-resistant modified polypropylene (PP), it provides structural resilience during wall strikes and crashes while keeping dry frame weight down to just 4.48g.
