BETAFPV 2pcs Air65 II 65mm Brushless Whoop Frame Kit for DIY Ultralight Weight 1S Micro Racing FPV Quadcopter compatible for Matrix 1S FC, 31mm/1219S Propellers 07xx 08xx Series Motors

The 2.65g Air65 II Frame: Co-developed with pilots, redefines lightweight agility.

R&D streamlined 6 arm braces to 4, optimised ducts, and boosted thrust by 5% while improving PID response. Its resilient PP matrix absorbs crash impacts, and refined details like screw protection and enlarged FC holes ensure durable, dominant performance for worry-free flying. Frame Reshaped: +5% Thrust; By strategically reducing arm braces from 6 to 4 and refining duct aerodynamics, the Air65 II achieves 5% 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 with <12ms lag, 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, enlarged 1.2mm FC holes fit 1.4mm screws effortlessly, and our 12.4mm lowered ducts (-0.6mm) plus 3.8mm slim profile clear short-can motors where pilot priorities meet engineering obsession
