BetaFPV Air65 II Brushless Whoop Frame
The BetaFPV Air65 II Brushless Whoop Frame is the upgrade your micro whoop has been waiting for, refined together with the global pilot community. It gives you more punch from the same motors and a smoother, more locked-in feel in every manoeuvre, so you can push harder through gaps and tight lines. And when a session ends in a crash, the tough frame shrugs it off, so you spend less time on repairs and more time in the air.
BetaFPV Air65 II Brushless Whoop Frame — Phenomenal Lightness and Precise Flight
The BetaFPV Air65 II Brushless Whoop Frame is a 65mm whoop frame made of PP that weighs just 2.65g. Compared with the first Air65 frame, it has 4 arm braces instead of 6 and redesigned 33mm ducts, which give 5% more thrust. The optimised connecting structure reduces frame vibration, and with Feedforward tuning BetaFPV achieved a near-perfect PID step response with under 12ms lag. The frame takes 31mm propellers, motors mounted with 3x M1.4 screws on a 6.6mm pattern and a flight controller with 25.5x25.5mm mounting holes, enlarged to 1.2mm so M1.4 screws fit. The battery slot measures 11.4x6.2mm and the maximum size of the frame is 82.6x82.6x15.1mm. BetaFPV uses it on the Air65 II Racing and Freestyle quadcopters. Available in five colours: Transparent, Black, Blue, Orange, Purple.
BetaFPV Air65 II Brushless Whoop Frame Key Features
- More Thrust - 4 arm braces instead of 6 and refined ducts give 5% more thrust than the first Air65, so the quad reacts to the throttle instantly.
- Less Vibration - The optimised connecting structure calms the frame, so the PID tune stays precise and the flight feels locked in.
- Crash-Ready Material - The optimised PP blend absorbs hard impacts, so you get back in the air after a crash instead of replacing the frame.
- Low Weight - Just 2.65g, even with the larger 33mm ducts, so the frame does not slow your whoop down.
- Pilot-Focused Details - Motor fixed slots, a screw protection structure and enlarged FC holes make the build easier and protect the motor screws.

BetaFPV Air65 II Brushless Whoop Frame Compared with the Air65
Frame Reshaped for 5% More Thrust
By reducing the arm braces from 6 to 4 and refining the duct aerodynamics, BetaFPV gave the Air65 II 5% more thrust than the first-generation Air65 frame. That means instant throttle response and sustained power. The manufacturer measured it in two setups, Air65 Racing (0702SE II 27000KV motors with GF 1219S propellers) and Air65 Freestyle (0702SE II 23000KV motors with HQ 31mm propellers).

Stable and Precise Flight
After dozens of structural refinements, the final connecting arm design of the BetaFPV Air65 II Brushless Whoop Frame effectively reduces frame vibration. Paired with Feedforward tuning, it achieves a near-perfect PID step response with under 12ms lag, for crisp manoeuvres and smooth freestyle flow.

Optimized Resilient Material
The optimised PP blend of the BetaFPV Air65 II Brushless Whoop Frame has been battle-tested in real FPV flying. It absorbs the energy of hard impacts, so the frame survives even violent freestyle crashes and you can get straight back in the air.

Details That Matter
Retained motor fixed slots keep the motors precisely aligned, and the new screw protection structure shields the motor screws in a crash. The FC holes are enlarged to 1.2mm so M1.4 screws fit effortlessly, and the ducts are lowered by 0.6mm to 12.4mm with a slim 3.8mm profile that clears short-can motors.
