SpeedyBee Bee35 Pro 3.5-Inch Frame

The SpeedyBee Bee35 Pro is a 3.5-inch cinewhoop frame engineered for smooth proximity flying and outdoor HD video capture. Built around tough, impact-resistant injection-moulded propeller guards, this frame is specifically tailored to house high-power digital video systems. The Pro edition integrates a custom CNC aluminium heatsink designed to wick heat away from transmitters like the DJI O3 Air Unit, preventing overheating on the bench or during low-speed flights.

Key features

• Tough injection-moulded prop guards for safe flight around obstacles and tight indoor spaces.

• Integrated CNC aluminium bottom-plate heatsink for rapid thermal management of digital VTX units.

• Vibration-isolated camera mount with an integrated aluminium lens protector designed for DJI O3 setups.

• Versatile electronics support with dual mounting patterns for both flight controllers and video transmitters.

This frame pairs well with 2004 to 2203.5 brushless motors and a 6S AIO flight controller. It generates enough thrust to carry a lightweight action camera, or you can rely purely on the DJI O3's onboard recording for an agile, sub-250g-capable build.
