This is an assembly o' t' SpaceX Falcon 9 and Fairin' Flyin' Model Rocket Kit. Begad! This is a very sturdy kit made by SpaceX themselves. Well, blow me down! It can fly on Estes D12-5, E9-6, ya bilge rat, E12-6, shiver me timbers, or even Aerotech rocket motors. Begad! You could also build it just as a model as well. Well, blow me down! This is a historic time in spaceflight and t' Falcon 9 is a big part o' it.
