Redneck Rocket Remix

thingiverse

I saw thinkin3D's Reneck Rocket on this here Thingiverse and thought "That's a mighty fine rocket there!". But then I reckoned I could do it a little better, or different anyway. So here is my Redneck Rocket Remix. This here remix uses a few parts from the original, most notably the part that the parachute gets tied to and the nosecone base. And the parts here can be used with parts from the original for the most part. Here are the differences... 1) I made the fins thicker. They're 2mm thick as opposed to 1mm thick. The little tab thingy is still 1mm thick, so these fins can still be used with the original motor can. But they'll need my new ring, which has thicker notches in it. 2) I added a dihedral to the bottom of the fins. This let's the rocket stand up when sitting on a table. I'm too lazy to make a stand fer it. 3) I removed the launch lug from the nose cone. That lug is fine for red necking a rocket and all, but lugs have no place on nose cones in my opinion. While at it, I made the nose cone taller. 4) I made a coupler to combine two Pringles cans. In my example, I used a regular and a snack can, but you can use any two cans. I put a launch lug on this coupler to compensate for the one I removed from the nose cone. This lets you make taller rockets AND eat more Pringles, so double win! Longer rockets are more stable. 4) I made another coupler without the lug in case you want to make something stupid long. But here's the real redneck magic... 5) I redesigned the fin can to use a screw on retainer, which will hold your D motor in there a little better. But it will also let you use Aerotech motors, which have a little lip on them. Aerotech motors go all the way to F! That's an F44-4 in that there photo. NOTE: Run a fillet of Epoxy along the root edge of both sides of each fin to secure them better to the Pringles can. Especially if you plan on using something bigger than a D. NOTE 2: You'll need to add weight to the nose. Do a swing test to determine how much. There's feller's on the Youtube that will explain how to do this. I added BB's to the nose with Epoxy 'cause modelling clay is too fancy for me. NOTE 3: E and F motors produce more thrust and pressure than D's. Yer rocket will probably be fine, but you'd better give everyone a heads up before launchin. EDIT 10/22/2018: Thickened the nosecone slightly to make it a little stronger in case of impacts. FLIGHT REPORT Flew this here rocket on a D12-3 today. Everything was looking good. Nice straight flight and all. But the dern chute failed to open and the rocket pancaked on a road and broke the nosecone and one of the fins off. I ken fix it, I spose, but dern it all! I wanted a perfect flight. At least I know it does work.
