FT Bloody Wonder V2

From the Flitetest Swappables Series, the Bloody Wonder is a simple three channel “Bank and Yank” style design. Beginners can outfit their plane with a small 24 gram motor to experience manageable speeds and excellent maneuverability. Place a larger motor on the same design and you will be able to rocket off vertically with blistering speed, while pulling a 75 ft streamer behind you.
