BetaFPV Air75 II Frame (Black)

The BetaFPV Air75 II Frame in black is a next-generation 75 mm brushless whoop frame built for pilots who want the perfect mix of ultra-low weight, sharp handling, and real crash durability. After more than a year of Air75 shaping the standard for lightweight agility, the new Air75 II takes things further with a refined 4 g design developed alongside the global FPV community. The result is a cleaner, lighter, and stronger platform made for fast indoor runs, technical freestyle, and everyday hassle-free flying.

Key Features

• Ultra-light 4.00 g frame for a highly agile and responsive 75 mm whoop build.
• Redesigned arm brace layout reduced from 6 to 4 supports, helping increase thrust by 11% compared to the previous generation.
• Optimized duct geometry and connecting structure reduce frame resonance and improve PID response.
• Durable PP material blend helps absorb hard crashes and everyday impacts.
• Pilot-focused details include motor mounting slots, motor screw protection, enlarged 25.5 x 25.5 mm FC mounting holes, and a lower-profile duct design.
• About 10% lighter than the first-generation Air75 frame.

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 delivers an 11% thrust increase over Gen 1. That means snappier throttle response, stronger punch, and more confident power delivery when your quad needs it most.

Built for Smooth, Reliable Flight

Dozens of structural refinements helped shape the final arm-connecting design, reducing frame vibration and lowering resonance. Paired with proper feedforward tuning, this gives the Air75 II a near-ideal PID step response for precise control, cleaner lines, and smooth freestyle performance.

Optimized Durable Material

The proven PP material blend is made to handle the realities of FPV flying. Concrete taps, gate clips, and rough crashes are all part of the game, and this frame is designed to take the hits and keep going. Fly harder, worry less, and spend more time in the air.

Details That Matter

Every gram and every shape has been carefully considered. The retained motor mounting slots help with precise alignment, the new motor screw protection structure helps deflect impact forces during crashes, and the enlarged FC holes make installation easier with 1.4 mm screws. It is a smart upgrade for pilots who care about clean builds, durability, and consistent performance.
