Valkyrie model rocket

thingiverse

In the not too distant future our solar system is besieged by the evil Qrill empire. To combat this threat the different nations of our planet unite to form the United Earth Space Force. Their front line fighter is the Valkyrie. Each Valkyrie is equipped with two photo bombs on it's wingtips and two railgun cannons in the nose. It's time to put the Qrill on the defensive!! Ok, I made all that up. If you don't like it, make your own story up. That's kind of the beauty of the thing. This rocket is tail heavy, you will need to add weight to the nose. How much weight is up to how long you make the body tube. I taped BBs to the nose and did swing tests with a D12-5 installed...kinda. Did you know a D12-5 weighs almost the exact same amount as 18 post 1986 pennies? It does! Anyway, I did the swing test and added BBs until it was stable. Then I drilled a hole in the base of the nose cone, dumped the BBs in, and drizzled in Epoxy to hold them in place. I've flown this on a C6-5 and D12-5 and both flights went well. It flies straight and true, though it will weathervane in the wind a bit with those big fin surfaces. BTW, be sure to fillet the fins where they go over the body tube for additional strength. As for the decals, print them on decal paper on your ink jet. I used the superior graphic design program "Microsoft Paint" to design them (yes, that was sarcasm), so they're a little crude. If you have something better, by all means, redesign them. Use mine as a template if you want. EDIT 5/8/2019: Added a variant of the fins that fit an Estes E size motor.
