I am working on my L1, and recently got a Loc-Precision MMA-2, 38-29mm Motor Adapter. Included with the parts is a 3/4" length of 38mm motor tube. There is no mention of the part in the instructions. I assume it is to be glued to the aft end of the adapter to act as a thrust ring. However, 3/4"...

I was heading for vacation with the family on the South Carolina coast last Saturday, and found myself driving through Orangeburg, SC. Pretty soon I saw a sign for Super Sod Farm. Thinking to myself that it seemed to me a lot of the TRF posters frequently talk about launching at a sod farm in...

The Backstory: Last summer after a 30 year hiatus I got back into the rocketry hobby. My son and I launched some of my 30+ year old rockets, and I was hooked again. I started doing a lot of research online, and came across a design on the JimZ website for a former Estes Design of the Month...
