Lab 03- Build Believer

For this weeks lab, me and my team continued on working on the believer drone and continued working on building and installing the motor mounts as well as the motors itself. After installing the motors, we started working on the D-Sub connector and soldering the servos as well as the ECS to these connectors. After reviewing the feedback from the other group we checked for imperfections in the build and continuied where the last group left off. The goal was to identify deficiencies, understand their root causes, and delevop a plan in oder to continue bulding our drone.

Step 1: The first step was to cut out indents in the motor housing and then test fix the motor housings in the wing. After testing this I then installed the motor and the motor housing onto the wing and then made sure everything pit perfectly

Step 2: After installing and fitting the motor, I then screwed the pieces together and then aligned the ESC wires and made sure both wings motos were fitted and bolted on correctly. After bolting on the motors, i then fitted the servo wires, as well as the ECS wires into the wing as a test fit and after moving the wires and threading them, everything came together.

Step 3: After test fitting all of the equipment, we then took it out and started focusing on the D-Sub connectors. We first solidered the servo wires for the ailerons and motor, then solidered the ESC wires to the D-Sub. The ESC directly provides current and function to the motor and is crucial in order for the believer to fly. It was difficult to match which wire goes to which D-Sub butafter looking at the manua lfor the Believer, we got the gist of where each wire goes.

We also used this page as a reference and as a wiring diagram for our beleiver drone in oder to see where things go. This page shows the D-Sub connectors pins and where they are located, as well as which pin locations is for what component.

⁠

Overall, This lab helped me understand how to properly solder D-Sub connectors as well as using a wiring diagram and physically aligning and test fitting components into our believer drone. I learned a lot about improvising when something does not seem to fit, the motor mounts were not aligned before and i had to use an exacto knife and cut some inlets so that the mounts are fit flush. Overall, this lab has helped me be a better team player as well as learning how to work hands on on fixed wing aircraft.
