In 5th grade, I did DI for the third year in a row. This time, the challenge was to build an aircraft that can move a payload across the stage repeatedly. This time, we made a quadcopter for our challenge. It was one of the most complex projects I have done, and it seemed like I always needed to learn a new skill or fix something. However, I was determined to make it work, and we got first place for elementary level in the regional competition.
