Three Propulsion Systems

The Air75 II expands its lineup with three distinct performance profiles: Champion, Racing, and Freestyle.Each version is powered by new 0802 brushless motors, featuring an industry-first 0.1mm stator core, specific magnetic and winding designs for superior efficiency and power. Combined with the new GF 1614 3-blade props and driven by the high-output Matrix 1S 5IN1 II Flight Controllerwith a 12A continuous (18A peak) ESCthis system is built to reliably meet extreme current demands.

The Champion is equipped with dualball bearing Champion 0802 Motors (28000KV) for maximum power, achieving an exceptional 7.1:1 thrusttoweight ratio for explosive acceleration and track dominance. The Racing features Racing 0802 Motors (25000KV) tuned for razorsharp throttle response and agility on technical courses. The Freestyle utilizes Freestyle 0802 Motors (22000KV) optimized for smooth control, superior lowend torque, and efficient, fluid flying.

Durability

Flight Controller

The Matrix 1S 5IN1 II FC employs a 3-point mounting system that creates cushioning space during impacts, reducing stress on core components and lowering the damage rate by up to 80%. Its 1.0mm thickened PCB and optimized layout further enhance crash resilience.

New Canopy & Frame

Every version is built on the same foundation: the Air II Canopy and the Air75 II Frame, featuring strategic reinforcements and upgraded materials. This combination ensures consistent durability and reliable performance in every flight.

Precision-Tuned Flying Experience

Every component, from the motor and propeller combination to the flight controller parameters, is meticulously calibrated for each version. This results in three distinct flying characters: the smooth, efficient Freestyle, the razor-sharp Racing, and the max-power Championensuring an optimized experience for every pilot and environment.
