The Foxwhoop 25 is a very well made 2.5" Cinewhooop frame. The frame is light (54 grams) and has durable plastic propeller guards. The Foxwhoop is an ideal choice for building a smaller copter designed to carry a lightweight HD camera (Naked GoPro) for indoor filming. Drone can be built with both analog and digital (Caddx Vista) image transmission.Through the pusher configuration, the propellers are better protected.
