• 58 °F.
• Clear skies.
• ~5mph, lowish winds.
• PerfectFlite Firefly altimeter.
• Every flight: Cesaroni Pro29 57F59-5A, we drilled 7 sec off of the initial 12sec delay.
• Every flight: new 3D printed rougher transition to try to add drag to lower the height.
• Every flight: Stability at ~2¼, too high probably.
• First flight: 650g (max allowed weight) - we added some coins in the new 3D printed cap.
• First flight: Added Velcro covering the fins and also wrapped around the transition, removed after this flight but it was in the highlighted part of the photo.
• Second flight: 637g no coins, we took off the Velcro wrapping the tube but still had all the velcro on the fins.
• Third flight: 623g no coins, we took off the Velcro on the inside side of the fins but left the more fuzzy Velcros on the farther out side.

Results:

• First flight: 651' apogee.
• First flight: 36 second duration.
• First flight: The rocket curved over to the side a lot on the flight up despite the low wind, it may have been because some of the long Velcro strips wrapped around the rocket were rubbing on the rail.


• Second flight: 761' apogee.
• Second flight: 44 second duration.
• Second flight: Unlike the first and third flight, the rocket went pretty straight up and didn't curve at all.


• Third flight: 771' apogee.
• Third flight: 48 second flight duration.
• Third flight: The rocket was also curving over on one side and if that didn't happen we probably would have gone higher.

One of our likely issues was that the stability was too high, even though the winds were low at the ground high up they were probably higher, maybe the Velcro was catching the air as well in unexpected ways. Our plan is to cut down the fins a little bit more to reduce the stability to maybe closer to 1¾. Especially on the last flight, our rocket curved way to one side while flying even though the delay was only slightly after apogee. Our bottom tube is also getting really beat up because we glued a new rope on so hopefully we can fix that.
