Description

BETAFPV Air75 II 75mm 1S Brushless Whoop Frame Kit for RC Micro FPV Racing Drone

The BETAFPV Air75 II Brushless Whoop Frame Kit is designed for RC Micro FPV racing enthusiasts seeking lightweight agility and durability. Weighing just 4g, this frame offers an 11% increase in thrust compared to its predecessor by reducing arm braces from six to four and optimizing duct geometry. The frame is constructed from a resilient PP blend, capable of withstanding the toughest crashes. Enhanced features include motor screw protection, enlarged flight controller mounting holes, and a lowered duct profile. These pilot-focused details ensure precise alignment and optimal performance, making the Air75 II a top choice for relentless, worry-free flying.

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 radcal 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 resilence. 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 Points:
– Arm 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 沁 25.5mm), and lowered duct profile.
– At just 4g, the Air75 II achieves a 10% weight reduction compared to Gen 1.
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.
Optimized Resilient Material:
Our battle-tested PP blend laughs off concrete kisses and tree bites. Survive your most violent freestyle crashes 藩 and fly home.
Details Matter:
Every 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.
