Frame for BetaFPV Pavo20 Pro with HD VTX holder (gray transparent) | O4 Pro

BetaFPV Pavo20 Pro Frame with HD VTX Mount (Transparent Gray) | O4 Pro

The BetaFPV Pavo20 Pro Brushless Whoop Frame is built for the 2.2-inch Pavo20 Pro cinewhoop and upgraded for creators who want a tough, lightweight, and HD-ready setup. Designed around a 93.7 mm wheelbase and made from impact-resistant PA12 with reinforced whoop ducts, this frame delivers an ideal balance of durability, aerodynamic efficiency, and freestyle performance.

With expanded compatibility for DJI O3 Air Unit, Caddx Vista, RunCam Link, and especially the DJI O4 Air Unit Pro, this version includes the dedicated O4 Pro mount for improved stability, cleaner installation, and excellent HD footage capture. It is a great choice for hobby pilots building a compact cinewhoop for cinematic cruising, smooth indoor lines, or punchy outdoor freestyle flights.

Key Features

• Made for the Pavo20 Pro 2.2" cinewhoop – optimized geometry for stable, responsive, and efficient flight.
• Impact-resistant PA12 reinforced ducts – thickened whoop channels improve crash resistance and overall frame strength.
• 8–11% thrust boost – aerodynamic duct design helps increase thrust compared to non-ducted designs.
• Optimized for 3S power systems – pairs especially well with a powerful setup for cinematic flying and freestyle action.
• Dedicated O4 Pro mount included – designed for the DJI O4 Air Unit Pro with enhanced structural support and clean fitment.
• Wide-angle camera mounting support – dual camera mounting holes for DJI O4 Pro and DJI O3 help maintain secure positioning and better angle stability.
• 0–40° camera tilt adjustment – optimized camera rotation point allows smooth and practical angle tuning.
• 30° angled antenna mounts – helps improve antenna routing and maintain strong signal performance.
• Quick HD VTX installation system – injection-molded mount enables fast assembly using just 8 screws, with no unnecessary adjustments.
• Pavo-series rubber dampening system – reduces vibration for smoother, cleaner HD footage.
• Flexible battery mounting – open battery strap slot with side guards keeps packs secure during aggressive maneuvers.
• ND filter support – designed to allow practical HD camera filter use.

Compatible with Popular HD VTX Systems

The Pavo20 Pro frame stands out with its highly versatile integrated HD VTX mounting system. It supports DJI O3 Air Unit, Caddx Vista, RunCam Link, and DJI O4 Air Unit Pro, giving hobby pilots more freedom when planning a build or future upgrade. The modular design allows quick switching between O3 and O4 Pro mounts without modifying the frame itself.

The hassle-free mounting system uses an injection-molded HD VTX bracket with built-in copper nuts, allowing the full setup to be assembled with only 8 screws. This helps maintain structural rigidity, improves vibration resistance, and supports stable, smooth HD recording across supported video systems.

Purpose-Built for HD VTX Performance

The O3 Air Unit mount and the new O4 Air Unit Pro mount were designed to maximize compatibility, durability, and performance for cinematic freestyle flying. Whether you are chasing clean footage, sharper turns, or a tidy electronics layout, this frame is engineered to keep your HD system secure and your build looking clean.

O4 Air Unit Pro Mount

Based on the proven O3 mount design, the new O4 Pro mount introduces several practical upgrades. Dual mounting holes improve the camera rotation center for smoother 0–40° tilt adjustment while maintaining excellent stability. The 30° angled antenna mounts are designed for stronger signal positioning and easier antenna replacement. The streamlined profile also allows easier access to ND filters, even when using a wide-angle setup. Altogether, these upgrades make the transition between O3 and O4 Pro systems simple while preserving the rugged character needed for freestyle flying.
