My rocket was inspired by an Estes Sliver. I planned to upscale it using a 3" mailing tube for the body. 1/8" balsa fins and a custom turned balsa nose cone and install a 38 mm motor mount to take advantage of the 38 mm G's available during the 29 mm engine drought. The fins will be overlayed with 3/4 oz fiberglass and epoxy resin.

The paint was designed to make the rocket highly visible during flight and recovery.

For decals , I planned to make them on my PC using a clear Avery 8 1/2" x 11" mailing label and I will water proof them with a mat spray used for inkjet photos. I have done this before and it worked really well. Unfortunately, my printer had to go in for repairs and the decals weren't ready at flight time.

To ensure a stable flight, I made slight increase in fin area and added 3" to the body length which will help with the static margin due to the weight of the 38 mm motor mount and a 38 mm motor. (safety first). I estimate an altitude of 1800' on a CTI G60.

This rocket can't be simmed by RocSim so I was forced to do it the old fashioned way, long hand calculations and a swing test. The rocket passed the swing test with flying colors and so I was set to launch.

The first flight was powered with an Aerotech F40 using a 6 second delay. I estimated the altitude at about 1800'. The chute opened on schedule, slightly after apogee, unfortunately it landed on a rock and a fin was in need of some glue.
