Mark4 10" V2 is a carbon frame designed for building a large 10" long-range quadcopter. The frame features a 473mm motor-to-motor diagonal and 7mm thick carbon arms that are interconnected for extra rigidity. It is designed for Micro-size (19mm) cameras, which are mounted in protective carbon side plates. The frame supports both 30.5x30.5mm and 20x20mm stacks. In the rear section, there is space reserved for a video transmitter, with mounting holes in 30.5x30mm, 25.5x25.5mm, and 20x20mm patterns. The motor mounts support both 16mm and 19mm M3 hole patterns. The frame is originally designed for analog video systems, but experienced builders can also install digital video transmitters without major issues.
