BetaFPV Air75 II Frame (Orange)

The BetaFPV Air75 II Frame is the next evolution of a legendary 75 mm whoop platform. Built together with the global FPV community, this updated version is lighter, sharper, and even more confidence-inspiring in the air. At just 4 g, the Air75 II delivers a 10% weight reduction compared to the previous generation, while its redesigned duct geometry and optimized arm structure unlock up to 11% more thrust. The result is a frame that feels snappy on throttle, precise in corners, and incredibly smooth for freestyle flights.

Designed for pilots who want to push harder without constantly worrying about durability, the Air75 II uses an optimized PP material blend that helps absorb impacts from crashes, tree hits, and rough landings. BetaFPV also refined the small details that matter in real-world use, including motor screw protection, enlarged flight controller mounting holes, and a lower-profile duct layout for improved overall performance.

Why Pilots Love the Air75 II

The Air75 II was reworked from the ground up to improve both flight feel and durability. By reducing the number of arm braces from 6 to 4 and refining the airflow through the ducts, BetaFPV created a frame that feels more alive in the air while staying tough enough for daily bashing. It is a great choice for pilots building a lightweight indoor ripper, a tight freestyle whoop, or a responsive backyard micro quad.

Redesigned Frame, 11% More Thrust

With a smarter brace layout and improved duct aerodynamics, the Air75 II produces 11% more thrust than the first-generation Air75 frame. That means faster throttle response, stronger punch-outs, and more usable power when you need it most.

Reliable, Locked-In Flight Performance

After multiple structural refinements, the final connecting-arm design helps reduce unwanted frame vibration. Combined with proper tuning and feedforward adjustment, this gives the Air75 II a highly controlled, clean PID response for precise lines, confident cornering, and buttery-smooth freestyle.

Optimized Tough Material

The proven PP material blend is built to take abuse. Concrete bumps, tree branches, and messy crash landings are all part of the hobby, and this frame is made to keep going so you can fly harder and worry less.

Details That Matter

Small upgrades make a big difference in day-to-day use. The retained motor mounting sockets help with accurate alignment, the motor screw protection structure helps deflect impact forces, and the enlarged ø1.2 mm FC mounting holes make it easier to fit ø1.4 mm screws during your build.
