BetaFPV Air65 II Champion frame (gray transparent)

Built to be the lightest 65 mm frame at just 2.20 g, the Air65 Champion frame sets a new benchmark for ultralight whoop builds without sacrificing durability. Its optimized ducts and reinforced structure help reduce frame vibration while improving thrust, resulting in near-perfect PID response and impressively agile handling. Made from durable materials and packed with builder-friendly details — from recessed motor slots to enlarged FC mounting holes — this frame is designed to survive hard crashes and make your next build easier.

Key Features

• Ultra-light 2.20 g weight — approximately 17% lighter than the Air65 II frame.
• Optimized structural bracing helps reduce frame resonance and supports cleaner PID response.
• Upgraded PP material blend improves crash resistance for demanding FPV sessions.
• Improved motor mounting design with enlarged 25.5 × 25.5 mm FC mounting holes for easier assembly.
• Lower-profile ducts and refined geometry help optimize airflow and prop efficiency.
• Ideal for 65 mm brushless whoop builds focused on low weight, fast response, and freestyle control.

2.20 g — The Lightest 65 mm Frame

Designed with one goal in mind — to become the lightest 65 mm frame without compromise — the Air65 Champion builds on the proven geometry and duct structure of the Air65 II and pushes performance even further. By reducing arm bracing and trimming excess material in key areas, it reaches an ultralight 2.20 g, which is 17% lighter than the Air65 II while maintaining an excellent balance between strength and weight savings.

Reliable Flight Performance

Made from durable materials that can handle heavy impacts and aggressive flying, the Air65 Champion frame is built for long-term use. Its arm structure, refined through multiple design optimizations, helps minimize frame vibration. Combined with Feedforward tuning, it delivers a near-ideal PID step response with latency below 12 ms, giving pilots sharper control, precise maneuvering, and an incredibly smooth freestyle flight feel.

Smart Details That Make It a Champion

Beyond weight reduction, this frame is packed with thoughtful design touches that simplify installation and maintenance. Recessed motor mounting slots make assembly easier, while the included M1.4×2 mm flat-head screws help reduce the risk of damage and keep the build looking clean. The enlarged 1.2 mm FC holes allow easy use of 1.4 mm screws. Lowered ducts at 12.4 mm and a slim 3.8 mm profile provide proper clearance for shorter motors while improving airflow for smooth and efficient propeller operation.
