Flyfish Fifty5 is a quality frame designed for freestyle and cinematic flying. The frame can hold up to 5.5" propellers. This allows it to provide more thrust than traditional 5" freestyle drones. This comes in handy especially when flying with heavier HD cameras like GoPro. The frame comes in true X configuration. The X layout makes the front and rear arms the same. Good symmetrical layout helps good flight characteristics. The Fifty5 aims for a lightweight, simple, but durable frame suitable for building both analog and digital drones.

The frame is cut from high-end T700 carbon, which has better strength than the commonly used carbon (T300). In addition, the arms are cut from 5mm thick carbon. The frame is very well made. The edges of the frame are beveled so there is no risk of cutting the cable on a sharp edge. The screws are made of durable grade 12.9 steel. The screws are pre-coated with Loctite, so the screws stay tight and do not loosen with vibration. The camera is protected by a metal bracket, made of the durable 7075 aluminum alloy commonly used on drones to make better motors. The camera has an adjustable angle of 15-60°. There are a number of 3D prints for the frame, including a shoulder protector or GoPro camera mount. On the top plate, the frame has a non-slip pad that increases friction between the frame and battery and minimizes the chance of the battery slipping out in a fall.

The frame has M3 mounting holes for 20x20mm and 30.5x30.5mm stacks. There is room for a second stack in the rear of the frame. The mounting holes are 20x20mm and 25,5x25,5mm M2. This allows the frame to accommodate an analog transmission as well as a Caddx Vista, Walksnail Avatar or DJI O3.
