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.

Favorite Rockets: The Launch Pad Osiris


I was a child of the 1960's and the dawning of the space-age. Aerospace and Astronomy were my passions then and still are to this day. Back then Model Rocketry was cool. Even science was cool. In the mid-70's I joined the Air Force and my rocketry went dormant for a while.

Fast forward to 1996. I moved to southern California (from Rochester NY) and I became a B.A.R. I was very active in ROC (NAR #538) from 1998 to 2002. In 2003/4 things changed professionally and again my rocketry went into storage. In 2010 things changed again, and rocketry came out of storage. So maybe I am a Born Again and Again Rocketeer. :)

I live in Southern CA with my wife and 6 wonderful kitties. I am a software architect specializing in Java and open source based web scale architectures.

Other activities I enjoy are building and flying wooden R/C Gliders (you know old school kits), R/C Helicopter... try to learn on the simulator, Astronomy, live theater, fine dining, cocktails, and wine tasting. I am an Atheist. Strangely I am not an amoral axe murderer, though apparently in religious circles I am considered so.

I enjoy all aspects of Rockets. 1/8A through M. I have just as much fun launching a MicroMaxx Rocket as a K impulse rocket.

Rocket Dungeon: A new approach to finless
A few days ago, one Dean Black posted a unique finless design on Facebook (members can join the NAR group and look for Dean's name). He describes the design as "induction stabilized." He also has a .pdf describing the rocket (again, you'd have to join and ask for it). There are several criteria which must be met for this to have any chance of working. Thus, I will generally describe the rocket but will not provide details until I've flown one and can personally vouch for it. His design is a two piece body with a central gap and no fins. The motor is in the top section. He claims two things ...

Model Rocket Building: Vern Estes Original Big Bertha
From a 2005 post by "A Fish Named Wallyum" on YORF - Here's some background on Vern Estes and the original Big Bertha. "Vern built this rocket to use at demonstration launches. It proved to be so popular that they later made it a free plan and then a kit. It became the largest selling rocket Estes ever made. I believe it is now also the "oldest" kit still made." In a recent post Bernard Cawley added: "It, along with many other things that Vern and Gleda have kept or collected, will be housed by the Museum of Flight in Seattle. The Stine archive is already there. Actually the first Big Bertha ...

Model Rocket Building: Jeff Taylor's Steampunked ACME Spitfire
Jeff Taylor (FatBoy on TRF) "Steampunked" his FlisKit ACME Spitfire. The finished results are amazing! CLICK HERE There are hundreds of rivets and plenty of cardstock trim. I especially like the shingles on the fin root edge and the Zebra wood veneers with barrel hoops on the upper section. The stand-off launch lug is hidden in the pipework on the right side. Jeff is donating the model to the NARAM 56 auction. If I were there, I'd bid on it! Turned 180 degrees shows more detail. Check out the screen on the lowest section shroud. The gauges add dimension and more detail. I thought the ...
