On Sunday, April 2, members from both teams traveled to the Great Meadow Virginia launch site for qualification flights.
This was the last day to qualify. The day was mostly sunny, around 60 degrees, with little wind. We got off 6 flights.
We used the site's launch rails. Objectives
- One qualification flight for the Red/White/Blue rocket at 415g with an E20-7.
- Two qualification flights for the New Red rocket at 315g with an E12-6.
Lessons
- The red rocket performed nicely for the two test flights, and the final qualification flight. All E20's had the same lot number.
- The new red rocket had issues, especially with deployment.
- The last flight of the new red rocket went straight, but way to high with no obvious reason. All E12 motors had the same lot number.
- Our use of the site's launch rail was acceptable because we always launched from the same rail and were able to keep it clean. Team 2662 did a little angle with the wind to get straighter flights.
- On reflection, the E12-6 may have been a bad choice for team 2661.
- We end the qualification flights with no eggs broken and no lost rockets.
