The 4g Air75 II Frame: Co-developed with pilots, elevates lightweight agility. R&D reduced 6 arm braces to 4, optimised ducts, and boosted thrust by 11% while refining PID response. A reinforced PP matrix absorbs crashes, and upgrades like screw protection, enlarged FC holes, and a sleeker duct profile ensure durability and dominance—engineered for relentless, worry-free flying
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
Reliable Flight: Following numerous structural refinements, our final connecting arm design effectively reduces frame vibration. Paired with Feedforward tuning, this achieves a near-perfect PID step response, translating to crisp manoeuvres and buttery-smooth freestyle flow
Optimised 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: 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
