On Monday, February 6, members from teams 1639 and 1641 traveled to the Walkersville launch site for test flights. The day was cloudy, cool, but with little wind. We used our 7ft launch rail. We conducted 6 flights. Objectives Test flights of all our team rockets. Refine our motor selection and recovery methods. Get ready for qualification flights. Lessons Team 1639 tried F39-6T motors with great success. The F44-8W was used for all the other launches. We need to order more of both. We had no issues with eggs breaking or recovery of rockets. Team 1639 black rocket had the booster separate. Team 1641 had an unexplained issue with flying too high. And their descent was still too fast. We lost video and pictures because the cold shuts down iPhones.
