Hey there, taking a sec to say hi as I am new to the forum, but not new to this fantastic hobby. I've been flying since I was about 6 and in the late 90's achieved my TRA L1 and L2. Then life kida took me in a different direction, however, now some 18 years later I am back. My girls and I started with some of my old Estes builds and mid-power stuff (yup my parents kept it all in their attic) but now I'm looking at getting back into HPR and to re-cert at L1. I still have my inventory of 29mm and 38mm Aerotech casings so that's a step in the right direction. Its cool to see how much has changed and how much has stayed the same. 1/2" launch rods have been replaced by rails, electronic dual deploy is now ultra common, and Vulcan Systems no longer makes motors, however, LOC and PML are still around with many of the venerable kits and Aerotech still makes the I-357 (one of my all time favorite motors) so I have some comfort there For those wondering about my SN, 'Theory' was the name of my first 4" scratch build and the rocket that I got my Cert 1 on in 1998. Flew on a Vulcan H-100. Theory II was the rocket that I got my Cert II on. Another 4" build. Weighed in at 54oz and flew on a J90. Popped the main at apogee via motor ejection. Made for a heck of a walk, but it worked. any way, just wanted to say hey.
