Since Mach 1 Rocketry first listed kits for preordering, I was very interested in his line of fiberglass low power rockets. I like working with fiberglass better than cardboard, and it also hold up to my curious 3 year old better than any Estes kit. Now, we have a line of fiberglass kits we can fly in the park on cheap BP motors. I bought a few kits this Spring when they were first offered and a few more during his Haloweeen / Black Friday Sale. First up, is the Mach 1 Exiter, a minimum diameter 3 Fin and a nosecone kit. Open Rocket shows it flying about 230ft on an A motor up to 2000 ft on a D. Sounds perfect for us. Step 1 is always to give the fiberglass parts a good bath. After the parts were washed, rinsed, and dry, I put them on the scale. 31g before any recovery. The kit includes a black printed streamer with the Mach 1 logo. I might use it, or I might use something more reflective if I end up sending it higher. Now the body tube was marked for the fin and rail button locations. The kit includes micro sized rail buttons for the Makerbeam rail or a launch lug. I like the appearance of buttons better than a launch lug. I don't see building a tower or fly away guides for a park flyer being worth the effort. Next steps, epoxy the thrust ring in place, rough of the area on the body tube for the fin roots and fillets, epoxy the fins in place. I think it will take longer to talk about this rocket than it will to build it.
