Description

The BetaFPV Air65 Champion Brushless Whoop Frame redefines micro-whoop performance with an ultra-light 2.20g design that delivers exceptional agility, faster response, and efficient thrust for precision indoor flying. Optimized ducts, reinforced connecting braces, and a durable PP structure minimize vibration while improving PID response, creating a resilient, crash-ready frame that simplifies builds, enhances airflow, and helps pilots push their tiny-whoop freestyle and racing performance to the next level.

Features

Diagram

Engineered with one goal—to be the lightest 65mm frame without compromise—the Air65 Champion takes the proven geometry and duct design of Air65 II and pushes it further. By reducing the arm braces and more, it achieves an ultra-light weight of just 2.20g—17% lighter than the Air65 II—a perfect balance between resilience and weight savings.

Reliable Flight

Built from resilient materials that withstand hard crashes and violent maneuvers, the Air65 Champion Frame is engineered for durability. Its connecting arm design—through dozens of structural refinements—effectively reduce frame vibration. Paired with Feedforward tuning, this achieves a near-perfect PID step response with <12ms lag – translating to crisp maneuvers and buttery-smooth freestyle flow.

Details That Make it Champion

Beyond weight savings, thoughtful design simplifies both building and maintenance. Dented motor mounting slots streamline installation, and the included flat-headed M1.4*2mm screws reduce the risk of damage and maintain a clean profile. Enlarged 1.2mm FC holes allow 1.4mm screws to fit effortlessly. Combined with 12.4mm lowered ducts and a 3.8mm slim profile, the frame ensures ample clearance for short-can motors and optimizes propeller airflow for smooth, efficient performance.

Package Includes

• 1 x  Air65 Champion Brushless Whoop Frame
• 15 * M1.4*2 flat head screws
