BetaFPV Pavo20 Pro O4 Air Unit Pro Whoop Frame

The Pavo20 Pro Brushless Whoop Frame is tailored for the 2.2″ Pavo20 Pro cinewhoop, now with expanded compatibility to support the DJI O3 Air Unit, Caddx Vista, RunCam Link, and the latest DJI O4 Air Unit Pro—paired seamlessly with the O4 Pro Bracket for enhanced stability and versatility. Designed with a 93.7mm wheelbase and constructed from crash-proof PA12 thickened whoop ducts, this frame combines durability with aerodynamic efficiency, delivering an 8-11% thrust boost. Perfectly paired with a robust 3S propulsion system, it generates unparalleled power for freestyle and cinematic flights. The frame also features dual camera fixed holes for DJI O3 and O4 Pro wide-angle shooting and the classic rubber damper design, ensuring buttery-smooth, HD footage every time.

Bullet Points

• Ultra-Durable PA12 Thickened Whoop Duct: Crash-proof construction with a reinforced cross-section design for superior strength and blast.

Compatibility with Popular HD VTX

The Pavo20 Pro Frame delivers unmatched versatility with integrated VTX bracket compatibility for DJI O3 Air Unit, Caddx Vista, RunCam Link, and DJI O4 Air Unit Pro. Its modular design enables rapid swaps between O3 and O4 Pro brackets, ensuring effortless VTX upgrades without frame modifications. The hassle-free installation system features an injection-molded HD VTX mount with embedded copper nuts, allowing the entire frame to be assembled securely with just 8 half-thread screws—eliminating tedious tightness adjustments while enhancing anti-vibration performance. This precision engineering preserves structural integrity, optimizes aerodynamics, and guarantees stable, smooth HD footage across all supported systems.

O4 Air Unit Pro Bracket

Building on the proven O3 Bracket, the new O4 Pro Bracket introduces several key improvements: dual fixing holes optimize the camera’s center of rotation for smooth 0-40° tilt adjustments while maintaining stability. The 30° angled antenna mounts ensure maximum signal strength and feature tool-free installation for quick antenna swaps. A redesigned streamlined profile provides unobstructed ND filter access, even in wide-angle shooting scenarios. These thoughtful upgrades make transitioning between O3 and O4 Pro systems seamless, offering pilots the perfect balance of cinematic precision and freestyle durability.
