BetaFPV Air75 II Brushless Whoop FrameBetaFPV Air75 II Brushless Whoop FrameFor 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 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.Bullet PointsArm 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.SpecificationsItem: Air75 II Brushless Whoop FrameMaterial: PPWeight: 4.00gWheelbase: 75mmMotor Mounting: 3-M1.4-6.6mmFlight Controller Mounting Hole: 25.5×25.5mmBattery Slot Size: 16.3×6.3mmMaximum Size: 99.1*99.1*16.2mmColor: Black, Transparent Blue, Transparent Orange, Transparent Purple, Transparent WhiteAir75 II Brushless Whoop FrameAir75 Brushless Whoop Frame Weight4.00g4.45gWheelbase75mm75mmDuct Diameter42.0mm42.5mmDuct Height4.5mm4.7mmArm Braces46Motor Fixed SlotSupportedSupportedScrew Protection StructureSupported Not SupportedPropellers40mm propellers40mm propellersDiagramFrame Reshaped: 11% ThrustBy 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 FlightAfter 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 MaterialOur battle-tested PP blend laughs off concrete kisses and tree bites. Survive your most violent freestyle crashes – and fly home.Details MatterEvery 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.
