Now, forged alongside our global pilot community, the lighter Air75 II Frame (4g) reimagines the form. Our R\u0026amp;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 shaves frame amplitude while adding 11% thrust and delivering near-perfect PID response. Beneath the form lies resilience. 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.\u003c\/p\u003e\n\u003ch5\u003eBullet Points\u003c\/h5\u003e\n\u003cp\u003eArm braces reduced from 6 to 4 + optimized duct geometry increase 11% thrust—while maintaining uncompromising durability.\u003c\/p\u003e\n\u003cp\u003eOptimized connecting braces reduce frame amplitude and achieve ideal PID step response.\u003c\/p\u003e\n\u003cp\u003eOptimized PP blend makes it crash ready.\u003c\/p\u003e\n\u003cp\u003ePilot-Focused Details: Motor fixed slots, motor screw protection structure, enlarged FC mounting holes (25.5 × 25.5mm), and lowered duct profile.\u003c\/p\u003e\n\u003cp\u003eAt just 4g, the Air75 II achieves a 10% weight reduction compared to Gen 1.\u003c\/p\u003e\n\u003ch5\u003eSpecifications\u003c\/h5\u003e\n\u003cp\u003eItem: Air75 II Brushless Whoop Frame\u003c\/p\u003e\n\u003cp\u003eMaterial: PP\u003c\/p\u003e\n\u003cp\u003eWeight: 4.00g\u003c\/p\u003e\n\u003cp\u003eWheelbase: 75mm\u003c\/p\u003e\n\u003cp\u003eMotor Mounting: 3-M1.4-6.6mm\u003c\/p\u003e\n\u003cp\u003eFlight Controller Mounting Hole: 25.5×25.5mm\u003c\/p\u003e\n\u003cp\u003eBattery Slot Size: 16.3×6.3mm\u003c\/p\u003e\n\u003cp\u003eMaximum Size: 99.1\u003cem\u003e99.1\u003c\/em\u003e16.2mm\u003c\/p\u003e\n\u003cp\u003eColor: Black, Transparent Blue, Transparent Orange, Transparent Purple, Transparent White\u003c\/p\u003e\n\u003ch5\u003eAir75 II Brushless Whoop Frame\u003c\/h5\u003e\n\u003cp\u003eWeight: 4.00g\u003c\/p\u003e\n\u003cp\u003eWheelbase: 75mm\u003c\/p\u003e\n\u003cp\u003eDuct Diameter: 42.0mm\u003c\/p\u003e\n\u003cp\u003eDuct Height: 4.5mm\u003c\/p\u003e\n\u003cp\u003eArm Braces: 4\u003c\/p\u003e\n\u003cp\u003eMotor Fixed Slot: Supported\u003c\/p\u003e\n\u003cp\u003eScrew Protection Structure: Supported\u003c\/p\u003e\n\u003cp\u003ePropellers: 40mm propellers\u003c\/p\u003e\n\u003ch5\u003eAir75 Brushless Whoop Frame\u003c\/h5\u003e\n\u003cp\u003eWeight: 4.45g\u003c\/p\u003e\n\u003cp\u003eWheelbase: 75mm\u003c\/p\u003e\n\u003cp\u003eDuct Diameter: 42.5mm\u003c\/p\u003e\n\u003cp\u003eDuct Height: 4.7mm\u003c\/p\u003e\n\u003cp\u003eArm Braces: 6\u003c\/p\u003e\n\u003cp\u003eMotor Fixed Slot: Supported\u003c\/p\u003e\n\u003cp\u003eScrew Protection Structure: Not Supported\u003c\/p\u003e\n\u003cp\u003ePropellers: 40mm propellers\u003c\/p\u003e\n\u003ch5\u003eFrame Reshaped: +11% Thrust\u003c\/h5\u003e\n\u003cp\u003eBy 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.\u003c\/p\u003e\n\u003ch5\u003eReliable Flight\u003c\/h5\u003e\n\u003cp\u003eAfter dozens of structural refinements, our final connecting arms design effectively reduce frame vibration.
