SpeedyBee Bee35 3.5-Inch Frame

The SpeedyBee Bee35 is a 3.5-inch cinewhoop frame engineered for smooth proximity flights and heavy-duty digital FPV systems. Correcting common thermal issues in enclosed whoops, it integrates a custom aluminium alloy heatsink to actively cool high-output video transmitters like the DJI O3 Air Unit or Walksnail Avatar during extended flights.

Key features

• Custom aluminium heatsink base designed specifically to prevent thermal throttling on high-power digital VTX units.
• Tough injection-moulded 3.5-inch prop guards with an aerodynamic profile for increased thrust efficiency and indoor safety.
• Silicone shock-absorbing mounts isolate the camera side plates, reducing high-frequency vibrations from reaching your HD camera.
• Versatile mounting options with dual hardware patterns for both the flight controller and video transmitter.
