BetaFPV Air75 II Brushless Whoop Frame

Here's a detailed description of the Air75 II Brushless Whoop Frame, created from your input in an easy-to-read format.

Air75 II: A new standard in lightness and power

The Air75 II frame is the result of extensive redesign and feedback from the pilot community. Weighing just 4.0 grams, it is 10% lighter than the first generation. The R&D team completely redesigned the beam structure and date geometry to achieve incredible gains in traction without losing strength.

Specifications

Material: Optimized impact-resistant polypropylene (PP).

Weight: 4.00 g (10% lighter than Gen 1).

Wheelbase: 75 mm.

Motor mounting: 3-M1.4 on a Ø6.6 mm chain.

Colors: Black, Transparent Blue, Orange, Purple, White, Gray.

Key improvements and design

Record efficiency: +11% thrust

Thanks to a change from a 6-beam to a 4-beam motor mount structure and improved duct aerodynamics, the Air75 II frame provides 11% more thrust than the previous model. This guarantees immediate throttle response and greater stability at high speeds.

Clarity of control and perfect PID

The new design of the connecting elements effectively dampens frame vibrations. This allows for near-perfect PID response, translating into extremely crisp maneuvers and freestyle smoothness.

Crash resistance

The use of a special polypropylene (PP) blend makes the frame very durable. It can withstand tough impacts against concrete or trees, allowing you to keep flying where other frames give up.

Important details for pilots

Screw protection: Added special structure to protect the motor screw heads from abrasion and impact.

Motor Fixed Slots: Motor Fixed Slots are retained to ensure perfect shaft alignment.

Enlarged FC Holes: 1.2mm holes allow you to easily use 1.4mm screws without extra effort.

Low Profile: Duck height has been reduced to 4.5mm for better weight centering and aerodynamics.
