Description:

For more than one year, the Air75 Frame defined lightweight agility. Now, forged alongside our global pilot community, the lighter Air75 II Frame (4g) reimagines the form. Our R&D team deconstructed every arm brace, duct geometry, and crash point. The result? A radcal yet refined frame: 4 arm braces replace 6, paired with optimized ducts and connecting structure. This shaves frame amplitude while adding 11% thrust and delivering near-perfect PID response. Beneath the form lies resilence. An optimized PP matrix absorbs brutal impacts from crashes. Refined details - screw protection structure, enlarged FC holes, and a lowered duct profile - ensure dominance. All engineered for relentless, worry-free flying.

 

Bullet Points:

- 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.

 

Frame Reshaped:

+11% Thrust: 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.

 

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.
