Dual-axis tilting quadrotor design v2

This redesigned dual-axis tilting quadrotor helicopter is a second attempt, featuring physically realizable aircraft with some limitations. The Turnigy DST700 BLDC motors provided by the university department were underpowered and required high RPM propellers for adequate thrust. Moreover, the frame was too heavy and flexible, necessitating reinforcement and weight reduction measures. Each revolute joint consisted of 3D printed parts that needed to be sub-assembled due to extrusion printing process. The 3D printed brackets were initially over-engineered but later resized. No force or torque calculations were applied for frame's structure, as the focus was on control application; hence, it could be either over-engineered or under-engineered.
