Brief:
This is Semroc's commemorative release for the 50 years of contributions to rocketry from Vernon and Gleda Estes, the founders of Estes model rockets. This was one of the first kits released by Estes. It is a unique design as it tumbles back to earth after flight. Each kit is assigned a unique number and can be registered at Semroc's website. The idea is to fly each of the gold painted kits in July as a tribute and the flier will receive a signed certificate from the Estes'.

Construction:
This is a simple, straightforward build. You get 1 body tube, 3 laser cut fins, balsa nosecone, launch lug, engine catch hook, retaining wire, and a Tyvek strip.

The instructions are clear and the experienced builder can construct this kit without them. Start with the preparation by sealing the nosecone and fins, sanding them smooth, and then rounding the leading edges of the fins. Next, glue the nosecone to the body tube. I used wood glue throughout the build. The engine catch hook bends at 90 degrees at each end, and the longer bend is pushed into the balsa nosecone. It is a good idea to use a strong pin to make a pilot hole. The body tube is pre-marked for alignment of the hook and for the fins. Glue the hook to the body tube, then glue the Tyvek strip over it to secure it. Be careful with the glue, I made a little bit of a mess with it. Next, glue the fins on the alignment lines. After the glue has dried, add the fillets. The last step is to glue the launch lug at the joint of the fin and body tube opposite the hook. The is also a retaining wire to glue to the body tube. It's purpose is to hold the motor in the body tube when the clips are attached to the igniter at launch time. The instructions also suggest adding a 1/32" by 3/16" wide strip of balsa opposite of the hook to prevent the motor from kicking out.

Finishing:
Since this is called the Golden Scout and it is a 50th anniversary commemorative, the natural selection of color is gold. I like to use Duplicolor high build for the primer coat. I applied a second coat after sanding, then sanded the Scout until the finish was smooth. I recently read that black or magenta makes for a good undercoat for gold so I used Krylon Gloss Black. After that coat dried, I finished with Krylon gold and the results were good. There are only two decals, one for the Sky of Gold event and the other being the unique kit number. This kit is #701.

Construction Rating: 5 out of 5

Flight:
The design or this rocket is a little different. When the motor's ejection charge fires, it will eject but is held by the engine hook which extends about 1.5" past the bottom of the body tube. This changes the center of gravity to where the Scout will tumble back to earth. It's a small rocket, so keep your eyes on it during flight. I will wait until July to put it skyward.

Flight Rating: NA

Summary:
I applaud Semroc for celebrating 50 years of model rocketry and this is a good way to do it. The Scout is certainly a classic kit and was the right choice for the project.

Overall Rating: 5 out of 5

    Brief: While buying some parts and supplies, I decided to go ahead and grab a Golden Scout to commemorate the Vern and Gleda's 50 years of contributions to this educational and fun hobby. Without their efforts, sport rocketry might not even exist today. There are already several good reviews here on EMRR, so I'll assume you've read them. There's no reason to repeat everything. ...

    ( Contributed - by Frank Casey - 03/29/08) Brief: This is a reproduction of the original Scout introduced by Vern Estes back in the 1960s. Back in the day, it sold for a mere 70 cents and introduced millions of people to model rocketry. Construction: Parts list: 1 balsa nose cone (BNC-30DE) 1 body tube (BT-30AP) 1 laser-cut fin set 1 engine catch hook ...

  • Semroc Golden Scout By Chan Stevens (March 6, 2008)

    Brief: The original Scout was designed by Vern Estes, and was awarded a patent in 1960 for achieving tumble recovery via a shifting CG. The motor slides back via the ejection charge. This became catalog # K-1 and is among the most beloved nostalgic designs. In celebration of the 50th anniversary of Model Rocketry, the "rocket doctor" Ken Montanye teamed up with Vern ...

Mike McFadden, Did you deliberately attach the fins to your Golden Scout in the wrong manner? I see no mention of why you did this in your review. I would have thought in appreciation of the way Vern designed this model most builders would show appreciation him by building the Scout as he originally intended.

I wonder why Mike McFadden glued his fins on by the trailing edge. He makes no mention in his article of a choice to be different--it looks pretty good with a really retro flair. I hope he'll let us know how it flies come July.

Mr. McFadden....You messed up! You glued the trailing edges of the fins to the tube instead of the root edges. I recommend not flying it that way. Although remembering the God-awful ruggedness of the Scout, it MIGHT fly and survive...
