Betafpv Pavo20 Pro Brushless 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.
• Aerodynamic Thrust Boost: Engineered airflow dynamics deliver an 8–11% thrust increase compared to ductless designs. Paired with LAVA 1104 Motors for explosive power, achieving up to 6’40” flight time.
• Upgraded Camera & Lens Protection: Dual camera fixing holes for DJI O4 Pro/O3 wide-angle shooting flexibility. Reinforced cam side panel guards against impacts and angle deviation, even after aggressive flights.
• New O4 Air Unit Pro Bracket: It retains all O3 Bracket features while adding dual fixing holes for optimized camera rotation (0-40° tilt) and 30° angled antenna mounts for stronger signal in a reinforced design.
• Hassle-Free HD VTX Mounting System: Integrated injection-molded bracket for hassle-free setup with just 8 screws—no tedious screw adjustments needed. Contoured antenna holder ensures secure, clean cable routing and maximum signal integrity.
• Pavo Series Rubber Damper Design: Proprietary vibration-damping system guarantees buttery-smooth, jitter-free HD footage in all flight modes.
• Versatile Battery Mounting System: Open-ended strap slot + side-limitation slots for a rock-solid battery grip. Accommodates a wide range of battery sizes while preventing shifts during hard maneuvers.

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.

Exclusively Sculpted for HD VTX

The O3 Air Unit Bracket and new O4 Air Unit Pro Bracket are designed to maximize compatibility and performance for cinematic freestyle flying.

O3 Air Unit Bracket

It feature 6 camera fixing holes, including dedicated wide-angle mounting positions to eliminate side-panel shadows and ensure unobstructed field-of-view capture, alongside a reinforced cam side panel that protects lenses while enabling tool-free vertical ND filter swaps. The optimized antenna holder secures cables for stable signal transmission, while the Pavo Series’ signature rubber damper design eradicates vibrations for jello-free footage.

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.
