The Center of gravity (CG), also known as the center of mass, and the center of pressure (CP)
In model rocketry you must ensure your rocket is stable. A stable rocket will fly perfectly, while an unstable rocket will fly in an unpredictable pattern possibly ruining the rocket, damaging property or hurting someone. Stability is extremely important when building a rocket from scratch, and a good idea to know how stable your kits are also.
Had some chuffs, bad ignitors, battery issues, CATOs and lawn darts.
It’s been a while since we’d got together for a launch, 07/03/21 was the last. Lots of rain and scheduling conflicts but it all worked out this weekend. It was in the low 80’s and overcast, for the first 2/3 of the launch, but the winds were mostly calm and we had fun.
Well, it wasn’t a great weather day as we barely got any sunshine and the high of 55 degrees was pretty chilly in the consistent wind. But as always we had a good time flying rockets!
Soggy, from the rain the day before, but a beautiful day. The temperature was 63, and in the sun felt warmer. The wind was light and the sky was mostly sunny until 3 pm when the clouds started rolling in for the evening rain. It was a great day for flying rockets.
Another great day for a launch. About 54 degrees and a little windy at times, made for a few long walks. Got a little chilly toward the end of the day but we had a great time.
Beautiful day, 72 degrees and low humidity, barely a breeze. Most of our flights landed close to the launch pads. Another great day flying rockets.
Rain? We left in the unpredicted rain, drove in the rain and arrived in the rain. Luckily, about 30 minutes after we arrived the rain stopped and we even got a little sun during the day. The wind was worse up in the sky so the rockets, under parachute, drifted a little far at times, but overall a great day and about 72 degrees.
Great day for a rocket launch! Beautiful fall weather, not a cloud in the sky, light winds and 73 degrees. We used the Jolly Logic AltimeterTwo on all ten of our flights.
Great launch today. Weather was a little too windy, but we managed, and the temperature was incredible, 70 degrees. The sky was overcast the entire day. We also had some CATO‘s.
Beautiful day, a little windy, made the temperature just right. We had a great time even though the opening day of dove season ran us off the main field.
