The device use as a reference, the hexarotor QWinOut F550 ,which is constituted by a frame of polymer (i'm trying with wood) ,6 brushless motors with three blades rotating in the clockwise and 3 in the opposite direction  each connected to its respective controller Electrónic speed (ESC) whose power is mediated by a flight controller Arducopter APM 2.8 (I have a commercial board expemption from my remote guru, Aristarco Cortés) . It uses integrated information to the vehicle as a barometer to estimate high, a GPS receiver for positioning and inertial measurement unit IMU estimating different axes orientation sensors.

* I designed and 3d printed six arms for my final drone, this is my final model made in SketchUp. I found a lot of problems with this solution because they where too weak and unstable during the flight. I had two option: redesign the whole drone and its programming, or use commercial arms. In that moment I understood that I wasn't prepared yet to make this project from scratch. I gathered some old arms that I had and continued with the internal programming of the drone.
