Semroc Saturn 1B

After teasing the rocketry community for nearly a year, Semroc finally released the reproduction 1/70th scale Saturn 1B just in time for Christmas. Faithfully reproduced based upon the 1967 Estes design (K-29), this kit is a very challenging but rewarding build. This is not for the faint hearted, nor for the rocketeer looking for a weekend project. Standard design calls for the original 4x18mm cluster although you can wimp out and use a 24mm single motor option as well.Don't expect it to be an exact match of the original though--the K-39 listed for $9.95 and currently fetches well above $100 on the open market today. The Semroc offering is available for a relatively modest $55.

Model Rocket Building: Asking Permission Might Be A Good Start!
If you follow the blog, you might recognize this rocket. It's my two engine cluster model called the Big Girtha. It was adapted from a Quest Big Betty kit. I took this picture before it was launched at the Tampa TTRA monthly. Then I saw it in a EBAY listing. Maybe I should be flattered, but I'm not. A vendor was selling his 808 "Spy" cameras using my picture. Farther down the Ebay listing is a link to my YouTube video from the flight. I didn't buy and build the rocket, buy the camera, fly it, edit the video and post it for somebody else to make a profit. Build your own model, fly your ...

Rocket Dungeon: Vintage rocket powered monocopter may be up for grabs
Early in my blogging days and near the peak of my fascination with monocopters, I found some photos of the Rotary Space Ship that was manufactured by the Brown Manufacturing Company in the '50s/60s. I was recently contacted by one Richard Moore, who has owned one since around then. He says he may be putting it up on eBay so, if anyone is interested, you should keep an eye out. If you want to make an offer before that, I can forward your contact info to him. He was also kind enough to provide some nice photos:

Model Rocket Building: New Products Reply From Estes John Boren
From John Boren (JumpJet on TRF): "Sorry I haven't posted in this thread yet but I couldn't find it and since I seldom go to the Watering Hole section it was by chance I found this thread since it was linked in another thread. As you can see my original question or statement if you wish to call it that instead, isn't an easy one to answer or for a company to act on. There are some common wants but for the most part everyone wants something different as their number one thing, which is common no matter what the topic is. I see more engines and parts are pretty much at the top of the list. ...

Greg Smith's Blog: Better living through additive manufacturing of a V2!!
Some of you know that I've been dabbling in 3D printing for three-ish years. I ceaselessly admire the astonishing progress of garage-based hardware hackers using intellectual property from patents that have expired in recent years. It appears that the masses using democratized technology continue to move far faster than the corporations that developed the IP in the first place!! One new startup, 3D Printer Works , arose from a successfully funded Kickstarter campaign. I like their style and recently ordered their first product, The CreatorBot 3D , for home use: And yes of course I upgraded ...
