To enhance the flying experience, DIY enthusiasts have diligently worked on reducing the weight of the 75mm whoop drones for an ultra-light structure. We upgraded the Meteor75 frame to the Air75 Brushless Whoop Frame, which achieves a remarkable minimum weight of just 4.45 grams. It maintains exceptional strength and durability while introducing a new Motor Fixed Slot and Motor Gasket, and optimizing a low-profile design. It indisputably emerges as the topgallant choice for pilots seeking an unparalleled ultra-light 75mm Whoop drone.

Bullet Points

Weighing merely 4.45g, this frame is 1g lighter than its previous version while maintaining robustness and durability.
With its new outer radial shape whoop duct structural design, is beneficial to weight reduction and wind resistance.
The Motor Fixed Slot limits ensure convenient and stable installation of motors.
By reducing the frame height, it effectively concentrates the lowered profile, delivering an enhanced flying experience.
The Motor Gasket allows seamless pairing with motors from different brands, effectively preventing propeller strikes. It is compatible with 07-08 series motors and 40mm propellers.
