BetaFPV Meteor 75 Air Brushless Whoop Frame




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 Meteor75 Air 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 Point

  • 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.

  • Compared with the spiral-shaped whoop duct, the outer radial shape requires less material and a smaller plane area, which is beneficial to weight reduction and wind resistance.
  • The weight is reduced from 5.6g to 4.45g, making the flight more flexible, exemplifying the exceptional ultra-light structure of the 75mm whoop drone. Both frames feature the same materials and durability.
  • With the low profile of the frame, the drone's gravity center is more concentrated and improves the sense of compactness. 

Motor Fixed Slot

In a groundbreaking development, the Meteor75 Air Brushless Whoop Frame has been added firstly with motor fixed slots, facilitating a more expedient and steadfast motor installation process. While misalignment has no measurable effect on motor efficiency, correct shaft alignment ensures the smooth, efficient transmission of power from the motor to the flight controller, reduces mechanical stress, and minimizes power wastage. For advanced pilots who have strict requirements for assembling the ultra-light 75mm whoop drone, this new design undoubtedly adds the finishing touch.

Motor Gasket

With a mere 1.2mm height, the Motor Gasket on the frame offers a range of features. Compatible with a wider range of motors to align prop lines used with other motors. prevents propeller strikes. Additionally, it effectively mitigates motor vibrations and noise transmission, reducing interference with other components. Acting as a protective barrier, it safeguards against dust, debris, and contaminants, thereby optimizing the drone's overall flight performance and stability.
