On Saturday, March 18, members from both teams traveled to the Walkersville park launch site for test flights.
We were joined by teams from BCC High School. The day was partially cloudy, about 40F, with light wind. The field was wet with snow. We got off 6 flights with varied results - one qualification flight. Objectives
- Qualify the Red rocket with E20-7 motors around 415g.
- Qualify the Pink rocket with weights around 315g using E12-6 motors.
Lessons
- It is hard to use a cell phone camera in the bright snow.
- We kept the launch rail straight up.
- The Pink rocket had igniters replaced several times.
- The Pink rocket landed hard on the first flight and cracked the body around the fins. We tried to tape it up, but then had a very poor flight. No qualification attempt.
- The Red rocket had a strange 2nd flight which may have been a launch rail issue. The third flight was better, but got tangled in descent.
- The final Red rocket flight was for qualification and had a very good score. The team spent time drying the recovery system and used a lot of baby powder.
- No eggs broken, and we recovered all rockets.
- We need another launch to complete qualification flights.
