For over a year, the  Air75 Frame  defined lightweight agility. Now, forged alongside our global pilot community, the lighter (4g) Air75 II frame re-imagines the form. Our R&D team deconstructed every arm brace, duct geometry, and crash point. The result? A radical yet refined frame: 4 arm braces replace 6, paired with optimized ducts and connecting structure. This slims the frame's footprint while adding 11% more thrust and delivering near-perfect PID response. Beneath the form lies resilience. Optimized PP matrix shrugs off brutal crash impacts. Refined details, screw protection structure, enlarged FC holes, and a lowered duct profile ensure dominance. All designed for relentless, worry-free flight.

Key Points

• Reduced arm braces from 6 to 4 + optimized duct geometry boost thrust by 11% while retaining uncompromising durability.

• Optimized connecting struts reduce frame resonance, delivering ideal PID step response.

• Optimized PP blend makes it ready for use.

• Pilot-centric details: fixed motor locations, 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.

Reliable Flight

After dozens of structural improvements, our final connecting arm design effectively reduces chassis vibration. Paired with Feedforward tuning, this achieves a near-perfect PID step response, translating to crisp maneuvers and buttery-smooth freestyle.

Optimized Resilient Material

Our field-tested PP blend shrugs off concrete embraces and tree-branch bites. Survive your nastiest freestyle tumbles and fly home.

Details Matter

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