Descon Easter Egg Rocket

Manufacturer:Scratch

Contributed by Dan Major

I get a big kick out of the challenge of making rockets from "found objects". I tend to walk through stores in a kind of a daze sometimes, wondering what sort of adapter or how much thrust it will take to "fly" certain objects on the store shelves. This is one of my recent attempts. Everything is found or made from scratch except the engine mount tube, centering ring, and thrust ring in the "nose cone" (launch lug was hand-rolled).



This is the completed rocket next to an 18mm engine casing


A shot with the nose cone off...


Showing the streamer...


And with the streamer folded and packed into place.

The egg gives interesting and fun flights from 200-300 feet. The streamer recovery can bring the rocket down a bit fast, esp. if it lands on concrete, so the construction needs to be robust (either that or you need to take a big bottle of CA glue to the range). Short delays work best as this thing has enough drag that it stops going up when the engine gives out.

Engines I've flown it on: first flight was on an A8-3. Just wanted to make sure it would fly. Then followed with B6- and C6-3 engines. The B engines really scoot off the pad, but I think the egg goes higher on a C. Be sure to tape the engine because this is a serious dart if the engine is spit out rather than the streamer.

Parts List: Plastic Easter Egg (mine is about 3" long by about 1 3/4 dia.), engine mount tube and thrust ring, paper centering ring, external coupling tube, 1/8" plexiglass (fins), launch lug, and streamer. The engine mount, centering ring, and green external coupler tube came from an Estes parts kit (engine mount kit?). Fins are 1 1/2" wide at the root, and have a span of 2" long. I just guessed at the curve aroung the egg and sanded until they fit. They are swept at about 30 degrees.

Construction note: the front half of the nose cone, forward of the thrust ring is filled with epoxy (you can see the ring left in the first picture where the epoxy heated and slightly melted the nosecone as it cured. This was done for several reasons. First to mount the green coupling ring. Since the area forward of the engine was so small, I thought that something was needed here to prevent the rocket from splitting rather than seperating at the seam. Second, it adds strength in case it lands on the tip of the nose. And third, to add weight to move the CG forward. The lips where the two halves snap together need to be sanded down so they pop apart easily.

Rocket N00b: When the World Met Big Bertha
Long ago, Estes Industries published a newsletter called Model Rocket News . This was long before I got into the hobby. This kept model rocketeers (mostly children in those days, though a lot of the information was very sophisticated, involving advanced mathematics and physics) up to date on the latest developments in rocketry, presented ideas for science fair projects, and allowed young rocketeers to present tips, feedback and ideas to both Estes and other rocket kids around the country. You can find issues in PDF form around the Internet (though I think a complete collection ...

Model Rocket Building: Simple Dual Deploy for LPR and MPR Rockets?
Soon to be released from Jolly Logic - THE CHUTE RELEASE "Chute Release is designed to be extremely easy to use. As a first step, you attach the tether to one of the parachute shroud lines (so that you don’t lose your Chute Release). Then, you gather the bottom of your parachute together and wrap the (rubber) band around it and snap the pin into the other side of chute release. That holds your parachute closed until you want it to open. Then you use the buttons to set an altitude. You can pack your chute however you like after that, including rolling it up." So as I understand it - ...

Rocket N00b: Igniter Tip - Q2G2s Keep Falling Out?
In May, I went to launch some rockets with Chad. I took along several I'd built but never flown before. It was breezy, and I lost a few. Against my better judgment, I put the Quest Quadrunner on the launch pad. This beauty of a rocket from Quest Aerospace is a four-motor cluster capable of pretty high altitudes for a model rocket. It took me a long time and some heartache to build, but in the end it turned out really beautiful. I installed four standard EC6-7 motors in the rocket. But clusters are tricky. The trick is getting all the motors to ignite at once. Estes motors ...

Rocket Dungeon: Estes MIRV Review
I didn't anticipate writing a post on this kit but now am even more fascinated with it. I hope to fly it this coming weekend and will fill in a flight report shortly thereafter. Overview This is a four stage rocket! Others may contest this fact but it has one booster and three parallel- staged sustainers. 3 + 1 = 4. That's my story and I'm sticking to it. The components are interesting for Estes. It has a plastic manifold to direct the blow-through from the booster to the three sustainers and the body sections are made from white foam. The foam dings easily but makes for a quick build and a ...
