I keep calling it my EZI-65 clone, but it's not a LOC rocket. I'm back into the hobby after a very long absence. I kept a bunch of my rockets from the 1980's and early 1990's. I have one in particular that I just can't remember who made it. It is a 4" rocket, LOC components, 57 3/4" long. The fin shape, payload bay (that's what we called them back then because there were no electronics) and such make it look almost exactly like a LOC EZI-65. And it weights about 3-lbs. So, very similar--but I know it's not a LOC kit.
Here is the interesting part that might tip off the manufacturer for you "experienced" folks. It came from the manufacturer with interchangeable motor mounts. The rear of the 4" body tube has a coupler installed to thicken the base of the rocket and make it essentially double-wall thickness. The fin tabs protrude through the wall of the tube/coupler combo, but only by 1/4". The fin tabs have some notches cut in them and you can insert a motor mount, turn it 20-45 degrees and lock it in place. Quite a cool design!
I loved (and still do) clusters, so this rocket really whispered to me all those years ago. : ) I bought a bunch of centering rings and made a bunch of motor mounts: single 38mm, single 54mm, dual 29mm, triple 38mm, 5X 29mm and one of my favorites, single 29mm with six 24mm around the outside. Can you say airstarts? I knew you could. You could make about whatever you wanted. Seems to be a lot like the current LOC MMA system.
So I picked this rocket up in the late 1980's or early 1990's--I can't really remember now. But for the life of me, I can't remember the manufacturer or the name of the rocket. Any ideas? I'm wracking my brain and in Openrocket, I'm calling it "EZI-65 clone" because I simply can't remember who made it. Here's a few pictures to get the ideas flowing. Thanks!
PS: The astute reader will notice the action shot I provided doesn't seem to have a symmetrical thrust plume. You would be correct in your assumption. This was a five-motor G flight and I obviously didn't get them all lit. Skywriting ensued, followed by a banged-up rocket. Picture from HOTSHOT (Georgia) back in 1994 at the sod farm for those of you who might remember back that far.
