Description

The BetaFPV Air75 II Brushless Whoop Frame (5 Colours) redefines ultra-light precision and strength for modern FPV pilots. Forged through pilot-driven innovation, this 4g frame delivers 11% more thrust, perfect PID response, and unmatched durability with a crash-ready PP blend. From refined duct geometry to screw protection and lowered ducts, every millimeter is optimized for agility, balance, and flight control mastery—engineered for pilots who demand relentless performance.

Features

• Arm braces reduced from 6 to 4 + optimized duct geometry increase 11% thrust—while maintaining uncompromising durability.
• Optimized connecting braces reduce frame amplitude and achieve ideal PID step response.
• Optimized PP blend makes it crash ready.
• Pilot-Focused Details: Motor fixed slots, motor screw protection structure, enlarged FC mounting holes (25.5 × 25.5mm), and lowered duct profile.
• At just 4g, the Air75 II achieves a 10% weight reduction compared to Gen 1.

By strategically reducing arm braces from 6 to 4 and refining duct aerodynamics, the Air75 II achieves 11% higher thrust versus Gen 1 –  delivering instant throttle response and sustained power for the quadcopter.

Reliable Flight

After dozens of structural refinements, our final connecting arms design effectively reduce frame vibration. Paired with Feedforward tuning, this achieves a near-perfect PID step response – translating to crisp maneuvers and buttery-smooth freestyle flow.

Optimized Resilient Material

Our battle-tested PP blend laughs off concrete kisses and tree bites. Survive your most violent freestyle crashes – and fly home.

Details Matter

Every gram perfected: Retained motor fixed slots ensure precise alignment, new motor screw protection structures deflect crash impacts, and enlarged 1.2mm FC holes fit 1.4mm screws effortlessly. Where pilot priorities meet engineering obsession.
