This documents t' build o' a 75mm 4-grain CTI M2250 C-Star motor for me Level 3 certification flight. Begad! I plan t' fly this in me Extreme WildMan at Red Glare XI this weekend. Well, blow me down! I never built a motor where I had t' glue t' grains into t' sleeve and I learned a few things along t' way. Arrr! It is long and a bit boring, but hopefully informative t' someone out there.
