BetaFPV Pavo20 Pro Brushless Whoop Frame for 2.2in Cinewhoop, O3/O4 Pro Brackets, 93.7mm

Overview

The BetaFPV Pavo20 Pro Brushless Whoop Frame is a brushless whoop frame tailored for the 2.2-inch Pavo20 Pro cinewhoop platform. It supports HD digital VTX installations including DJI O3 Air Unit, Caddx Vista, RunCam Link, and DJI O4 Air Unit Pro (with the dedicated O4 Air Unit Pro Bracket). With a 93.7mm wheelbase and crash-resistant PA12 thickened whoop ducts, this frame is designed for durable freestyle and cinematic builds, while maintaining a compact ducted profile.

Key Features

• PA12 thickened whoop duct with reinforced cross-section for improved impact resistance.
• Aerodynamic duct design claimed to deliver an 8–11% thrust increase versus ductless designs.
• Dual camera fixing holes for DJI O3 / O4 Pro wide-angle shooting flexibility, plus reinforced camera side panel protection.
• O4 Air Unit Pro Bracket adds dual fixing holes for stable camera rotation and 0–40° tilt adjustment, plus 30° angled antenna mounts for tool-free swaps.
• Hassle-free HD VTX mounting using an injection-molded bracket and embedded copper nuts; frame assembly uses 8 half-thread screws.
• Pavo series rubber damper vibration-damping design to reduce jello in HD footage.
• Battery mounting system with open-ended strap slot and side-limitation slots to reduce battery shift.
