Developer Modular X4 Quadcopter

X4 Developer Quadcopter Carbon fiber sheet pieces, 25mm carbon fiber booms and 25mm plastic boom clamps. Recommended configuration: - 4x T-Motor 3515-400 (or equivalent) - 4x Turnigy 40A Plush (or equivalent) - 4x Xoar 16x5 PJP-N props (or equivalent) - 2x 6S 5.000mAh 25C in parallel This is a modular X4 quadcopter drone designed for development, research and studies for universities, researchers, etc. It has a modular frame with good space for electronics, dual battery setup and a bottom mount for a wide variety of sensors. As a example in this design there is a Pixhawk Cube autopilot with a Odroid XU4 companion computer (computer vision, etc) and dual GPS antenna setup. It is possible to mount other sensors and autopilots with a little modification in the mount holes. The bottom sensor used as example is a Hokuyo UTM 30LX Lidar. I used several models from GrabCAD community like the hokuyo lidar sensor, ESCs, props, etc (Thanks a lot to the community).
