Flex25 HD from Speedy Bee


Let's go back to the drawing board cinewhoop's wheelbase is limited to its prop size. You can't go smaller than 109mm wheelbase if 2.5' props is what you want. Our solution? We placed the motors at different levels to greatly reduce the overall wheelbase, while still getting the power of a 2.5" props! At a 78mm wheelbase (similar to a tiny whoop!), you can carry your lightweight action cams with more confidence for that tight cinematic shots.

For digital pilots, get this quad with the most advanced 120fps RunCam Link Falcon Nano Kit digital FPV system, built with the original DJI ISP & 4:3 sensor which has the best image quality and 28ms low latency. Change the brightness, saturation, and other settings in your DJI FPV goggles wirelessly anytime you want.

Say goodbye to broken ducts! Proven with extensive tests, this new unibody protective duct made of car bumper material will make sure your quad from impact in the most extreme shooting conditions. Reinforced with M2.5 hex standoffs and M2.5 screws, this quad will definitely be the toughest 2.5 inch cinewhoop in your FPV fleet.

While other brands are still using outdated F4 20A AIO flight controllers, we built our AlO FC with the high-end STM32F745 MCU and complement it with the powerful 35A Bluejay ESC. And forget the annoying USB cables and inaccessible USB ports. Just power the quad, connect the SpeedyBee app via Bluetooth and configure everything on your FC and ESC with just a smartphone. You could even flash the firmware for both FC and ESC, or tinker with your quad wirelessly anytime, anywhere.

Swap from Naked GoPro, RunCam Thumb, and Insta360 Go quickly with 4 different cables* included in the package. The AUX 4 is configured for recording control - connect your action camera with the cable provided and start recording remotely using your radio. How's that for convenience?
