Lab 05 - Believer Familiarization
Summary
This lab was a group project that introduced me to the Believer airframe - a training platform for the Windracers Ultra. I worked in a group of five people, where we labeled the parts from the kit, learned about their functions, and how they work in the aircraft. Additionally, we examined two example Bills of Materials with potential electronic choices for the aircraft. We classified what each component’s purpose was in the aircraft, and discussed why one may have been chosen over the others. After reviewing and documenting those resources and parts, our final task was to streamline an existing build guide in a way that was shorter while remaining useful and comprehensive.

Reflection
In this lab we often have to work as groups for activities like flight labs or assembling aircraft like the M300, however, we also rely on each other to fill the gaps in knowledge we have in labs like soldering, where a quick response from a classmate could offer a different perspective than how it’s taught. This lab is a prime example of this. Andrew L and I were the most experienced in terms of electronics background or familiarity with these sorts of parts, but Andrew H, Hunter, and Lucas were much more willing to ask questions or point out things that seemed out of place compared to us. These different strengths are why we were able to be so efficient and productive, and we were ultimately able to communicate well and clearly, filling in any knowledge gaps the others may have had.
