The Flex25 Cinewhoop from Speedy Bee employs a unique design allowing it to use 2.5" props on a frame with a wheelbase of just 78mm (similar to tiny whoop). By placing the motors at different levels, the Flex25 makes room for 2.5" propellers on a craft that usually could only use 2" propellers. Along with this design, Speedy Bee has gathered some of the best gear to round out this PNP Cinewhoop. Just add your own receiver or have us add one to get in the air.
