This was me first Open Rocket design. Well, blow me down!  Basically three fins and a nose cone (3FNC) styled after t' Binder Design "Spike" but with a 24mm motor mount. Arrr! I put a lot o' effort into gettin' t' fins on straight and have been rewarded with amazingly straight flights - no rotation at all. Avast, me proud beauty!  Nephew Wes named it "Blue Thunder".
