BETAFPV Air75 II Brushless Whoop Frame-75mm FPV Racing Drone Frame Kit Accessories

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 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.
nBullet Points
n• Arm braces reduced from 6 to 4 + optimized duct geometry increase 11% thrust—while maintaining uncompromising durability.
n• Optimized connecting braces reduce frame amplitude and achieve ideal PID step response.
n• Optimized PP blend makes it crash ready.
n• Pilot-Focused Details: Motor fixed slots, motor screw protection structure, enlarged FC mounting holes (25.5 × 25.5mm), and lowered duct profile.
n• At just 4g, the Air75 II achieves a 10% weight reduction compared to Gen 1.

nDiagram
nFrame Reshaped: +11% Thrust
nBy 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.
nReliable Flight
nAfter 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.
nOptimized Resilient Material
nOur battle-tested PP blend laughs off concrete kisses and tree bites. Survive your most violent freestyle crashes – and fly home.
nDetails Matter
nEvery 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.
