SpeedyBee Flex25 2.5-inch Frame Kit

£39.99

Ultra-compact 2.5” cinewhoop frame with overlapping prop design, delivering big power in a smaller footprint.

The SpeedyBee Flex25 Frame Kit redefines what a 2.5-inch cinewhoop can be, packing the performance of larger props into a significantly more compact design. By using a unique staggered motor layout, the props partially overlap, allowing the frame to achieve a wheelbase around 28% smaller than typical 2.5” whoops while maintaining strong thrust and efficiency.

This innovative design results in a highly agile and compact drone that still delivers the smooth, controlled flight characteristics expected from a ducted cinewhoop—ideal for tight indoor flying, proximity freestyle, and cinematic footage.

The frame features a durable 2.5mm carbon fibre core combined with a full propeller protection duct, offering both strength and safety for close-range flying. A 1mm flight controller protection board is also included, helping shield sensitive electronics during crashes or hard landings.

Designed for modern compact builds, the Flex25 supports a 25.5×25.5mm AIO flight controller and a 14mm nano camera, making it compatible with a wide range of lightweight components. The layout also includes clearly defined mounting positions for the battery, receiver, antenna, and VTX, keeping builds clean and efficient.

Two versions are available, each tailored to different FPV systems:

Available Versions:

Analog Version – Includes TPU mounts for analogue VTX and antenna, with a dedicated mounting position for compact analogue transmitters (approx. 25–28mm width)

HD Version – Includes TPU mounts for HD systems such as RunCam Link, with dedicated top and bottom mounting options and support for 6-pin HD camera connections

Both versions include version-specific TPU components, ensuring proper fit and clean installation depending on your chosen video system.

Notes:

Frame kit only – electronics, motors, and VTX not included

Analog and HD versions include different TPU mounts depending on configuration

Ensure compatibility with your chosen camera and VTX system before building
