BetaFPV Air75 Brushless Whoop Frame

The Air75 frame is a premium choice for pilots looking to create an ultra-light 75mm voop. Weighing just 4.45 grams, it's a full gram lighter than its predecessor, the Meteor75. This update focuses on reducing wind resistance, increasing strength, and ensuring components are perfectly aligned for stable flight.

Key benefits and design

Aerodynamics and weight

The new outer radial shape allows the use of less material, which not only reduces weight, but also significantly reduces wind resistance. The frame has become more flexible in control, while maintaining resistance to hard falls.

Low-Profile

By reducing the height of the frame (from 16.5mm to 15.6mm), the drone's center of gravity has become more concentrated. This improves the compact feel and makes the drone more compliant when performing acrobatic maneuvers.

Fixing engines and gaskets

Motor Fixed Slot: Motor Fixed Slots simplify assembly and ensure precise shaft alignment. This reduces mechanical stress on components and prevents power loss.

Motor Gasket: The kit includes 1.2 mm high gaskets that protect the propellers from hitting the frame, absorb vibrations and noise, and also protect the motors from dirt.

Comparison with Meteor75

The Air75 shows significant progress, with weight dropping from 5.68g to 4.45g and the height of the rings being reduced, giving the drone a lower overall silhouette. New 44.5mm propeller guard design provides excellent compatibility with 40mm blades and 07-08 series motors.
