On Saturday, March 14, 2 members from two teams traveled to Walkersville MD to conduct some test launches. The day was cloudy, with almost no wind. We used our 7ft launch rail to conduct 3 flights. Objectives
- Test Team 15266 and Team 15406 primary rockets.
- Use E30s and 15 inch chutes with spill holes..
Lessons
- Both rockets flew very nice and straight with E30s;.
- They tried rocket weights around 365 grams, which seems to be about right for 800 ft.
- The 15 inch chutes took too long to descend. They may want to use 12 inch chutes our much bigger spill holes.
- Good flights when there is no wind.
- Walkersville is a nice launch field.
- With a little tweak, they are ready to qualify.
