Fresh out the build queue and with plenty of pics for your viewing pleasure. I have fond memories of the SSRS/Crown Lasor-114 and 134 sounding rockets. I flew my first composite F and G motors in these two kits back in the early 80's. The originals had nose cones and bulkheads turned from solid hemlock with plywood fins and heavy walled tubing.

The version I just built has a solid basswood nose cone from Sandman and uses Semroc LT-125 airframe tubing with a 29mm motor mount (LT-115). I cut a piece of 1-1/4" dowel rod to 3-1/2" long for the solid wood bulkhead and the fins were cut from 1/16" plywood. The original had surface mounted fins, mine mount TTW to the motor mount. I also used a Semroc baffle designed for ST13 and turned the o.d. down slightly with a dremel and sanding drum for a perfect fit inside the LT-125 airframe and to attach my kevlar shock cord mount to.

Last one I flew was over ten years ago and I always had a pretty good sucess rate for recovery using at least 10 feet of 2" wide mylar streamers and launched from a large field.

Some history and the Crown "philosophy" can be found on Ninfinger here as well as a starter set that included the E45 and awesome F67 composite motors:

In the pictures below the Lasor-114 on the FSI launch pad and the flight photo are from 1988 of my last original on a vintage Crown F67-12 low smoke composite motor. All the other pictures are from my current build. Also attached an interesting photo I found of Gary R. with Mark Mayhle the founder of SSRS/Crown. It's been so long I don't remember where I obtained this picture but I also saved the caption that went with it:

"Mark Mayhle on the left watches as Gary and Bob DelPrincipe prep a 2650 for launch at NARAM-16 1974 . Gary tells us that Mark started a company called Small Sounding Rocket Systems which later became Crown Rocket Technology and produced some of the first composite rocket engines after Enerjet".

Anyone else notice the similarity of the fin shape of the Lasor Series rockets compared to the fins of an orginal EnerJet 2650?
