Overall Rating:

Contributed by Bill Eichelberger


The Semroc Micron was part of my first order from Semroc back in 2003.  I built it and the Skyhook side by side, and because of these two became enamored with the Semroc way.  The sleek Skyhook and the sturdy Micron combined the best that was available in the hobby at the time, reproductions of classic kits with updated recovery systems and laser cut fins.  Rocketry Nirvana, and I inhaled deeply.


  • ST-7 body tube
  • Balsa nose cone
  • Laser cut fin sheet
  • Screw eye
  • Thrust ring
  • Kevlar and elastic shock cords
  • Crepe paper streamer

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 ...
