BetaFPV Air75 II Frame (White)

The BetaFPV Air75 II Frame is the next evolution of a fan-favorite 75 mm whoop platform—lighter, sharper, and built to take a beating. Developed together with BetaFPV’s global pilot community, this redesigned frame weighs just 4 g and delivers an impressive 11% thrust increase compared to the previous generation. With refined duct geometry, a reworked connecting structure, and fewer but better-optimized arm braces, the Air75 II is made for pilots who want fast throttle response, cleaner handling, and worry-free freestyle sessions.

Key Features

• Ultra-light 4 g design with around 10% lower weight than the Gen 1 frame.
• 11% more thrust thanks to reduced arm braces and optimized duct geometry.
• Improved frame stiffness and lower vibration for cleaner PID response and more precise flight feel.
• Durable PP material helps absorb impacts and survive hard crashes.
• Pilot-focused details including motor mounting slots, motor screw protection, enlarged FC mounting holes, and a lower-profile duct design.
• Built for 40 mm props and a 75 mm wheelbase, making it a great choice for lightweight brushless whoop builds.

Frame Diagram

Redesigned Frame, 11% More Thrust

By strategically reducing the number of arm braces from 6 to 4 and refining the duct aerodynamics, the Air75 II boosts thrust by 11% over Gen 1. The result is snappier throttle response, stronger lift, and more confident performance in tight indoor lines or aggressive backyard freestyle.

Smooth, Reliable Flight Performance

After multiple structural refinements, the final connecting-arm design helps reduce frame vibration and unwanted resonance. Combined with proper feedforward tuning, this gives the Air75 II an impressively clean PID response for precise control, locked-in cornering, and smooth freestyle flow.

Optimized Durable Material

The proven PP material blend is built for real-world flying. Whether you clip concrete, bounce off furniture, or tag a tree branch mid-pack, this frame is designed to handle repeated crashes and keep your whoop in the air longer.

Details That Matter

Every gram and every mounting point has been carefully considered. The retained motor mounting slots help with precise alignment, the new motor screw protection structure helps deflect impact forces, and the enlarged FC holes make installation easier with 1.4 mm screws. It’s a smart little upgrade for pilots who care about both durability and build convenience.
