BETAFPV Pavo Femto Whoop Frame Duct (DJI O4) – Black
Lightweight Propeller Protection for Your Pavo Femto
The BETAFPV Pavo Femto Whoop Frame Duct is a replacement component designed for the compact Pavo Femto FPV drone frame. It surrounds the propellers, providing protection while supporting efficient airflow during flight.
Manufactured from PA12 material, the duct combines durability with an exceptionally low weight of just 8.64 g. Its lightweight construction makes it suitable for FPV builds where keeping overall weight to a minimum is essential.
Designed for the 75 mm wheelbase Pavo Femto frame, this black replacement duct allows you to restore a damaged propeller guard without replacing the entire frame assembly.
Optimized Aerodynamics – Approximately 4% More Thrust
Inspired by the aerodynamic principles of rocket engine nozzles, the Pavo Femto duct features a carefully optimized profile designed to improve airflow around the propellers.
Its refined height and wall thickness contribute to improved aerodynamic efficiency. According to the manufacturer's specifications, this design provides an approximately 4% increase in thrust compared with the previous construction.
The result is a compact propeller guard designed to support efficient propulsion while maintaining the small dimensions and low weight required for agile FPV flight.
Improved Mounting Design
The Pavo Femto frame introduces an improved connection between the Whoop duct and the carbon fiber frame plate. Additional supports and positioning features help align the components correctly during assembly.
This reinforced connection supports a secure fit and helps maintain structural stability during dynamic FPV maneuvers.
The replacement duct is designed to integrate with the original Pavo Femto frame construction, making it a practical solution for repairing or rebuilding the drone.
Designed for the DJI O4 Pavo Femto Platform
The Whoop duct forms part of the BETAFPV Pavo Femto frame system developed for builds using the DJI O4 Air Unit. In the complete frame assembly, it works alongside the carbon fiber plate and the dedicated video transmission unit mount.
This product is supplied as an individual replacement duct. The carbon fiber plate, DJI O4 mounting bracket, electronic components and other parts of the complete frame are not included.
