Weekly report from team B. The first thing we did this week was to finish the work on the wing. We completed the additional part on wing-body joint and put a film on the entire wing. At this point, we realized that the work on electrical components needed more time, and decided to glue the wings and the propeller (with a motor) onto the body carbon pipe. Meanwhile, we continued to work on the electrical components. Eventually we were able to complete works on the electrical constituents including soldering the parts and handling batteries. Now, we are glad that our airplane was completed before the date of test flight and looking forward to seeing the plane fly.
