Greg's Next Big Project
I was very impressed with this ProLine X15 kit I saw in Extreme Rocketry. So I have ordered one from Hangar 11.
It is 6 inches diameter and 6 feet long!
Checkout the blog I have created for the project.

More Mighty Mo M Flight Data
I took the perfectflite MAWD data for the AMW 1350, AMW 1480 and AMW 1850 flights and lined up the plots.
Note the 1850 flight the Main did not deploy due to a rubber band I left on the deployment bag. Fortunately the Main shroudline tangled with the nosecone shockcord. So the entire rocket came down on the 5 foot TAC-9 chute. Oh yes, I am very lucky there was no damage. The soft ground helped.
I also left a rubberband on the drogue on the 1350 flight. So it had no drogue. I am definitely leaving the rubberband out for future flights.
I think the extra thrust on the 1850 made for more drag and a lower altitude.
No doubt the 1480 flight was technically the best. However, for visual effect and the longer burn my favorite was the 1350.

Oregon Scientific ATC-2K Digital Camera Review
I wrote a review for the ATC-2K on EMRR. This ties in with my submission for the EMRR Rocket Video Contest. Entries will be judged by EMRR Guests during a voting week starting July 30, 2007.

The Mighty Mo at Samson
I launched the Mighty Mo at the July 7th SEARS Launch. Several of my work mates from Panama City came up for the launch.
The motor was the AMW M1850 Green Gorilla. I had a scarry recovery because the main chute did not come out of the deployment bag. The whole rocket came down on the nosecone chute. At least it was all under chute. It made a big thunk when it hit but there was no damage. I had some rubber bands one the deployment bag that may have retarded the main chute from coming out.
Lesson learned leave the rubber bands off the recovery system. I also had a rubber band around my drogue on the first Mighty Mo Launch which kept it from opening. I had the ATC-2K on the rocket and the impact broke it off the mount. The mount was plastic. Now I will need to come up with an improved mount. Of course I did get a video.
