Pop lugs, not drugs
In order to prepare for L2 sometime in the future, I decided to practice construction and deployment techniques on a fleet of modified Pro Series II mid-power rockets. If mistakes occur, I lose a $40 rockets and a month's work instead of a $400 rocket with at least a couple moths work. This Leviathan refit is where I'll practice internal fin fillets, tube slotting, Chute-release use, and an accessible/replaceable shock cord mount. Possibly adjustable nose weight as well if I want to fly motors larger than a small H.
The Leviathan is without a doubt my favorite Pro Series II rocket. Simple, stocky, durable, and it flies well built to instructions (in fact too well sometimes). I built the original BroncBuster two years ago and launched it from the middle of a crop irrigation circle on an Estes G80-7T because it was the biggest motor I could get. Perfect boost, high deployment, steady descent. Unfortunately, I had painted it dark green and orange (school colors) and an incoming front blew it into a citrus orchard (which also happens to be dark green and orange). To this day, I know not where it hangeth.
Since the Leviathan was discontinued, I ended up buying the Scion when I read on the forum that its basically just a cheaper Leviathan with a longer unslotted tube (even has the 4th fin). When I received it I cut the rear tube down to the proper length and set out to make a 4-fin slot template using Solidworks drawings. This turned out harder than I thought it would because some printers demonstrate asymmetry along the feed axis on their paper. I went through several template iterations before I got one with the proper geometry.
An aluminum angle (angluminum?) and Xacto made the fin slots go smoothly, and the aft section finally came together for a dry fit. Which naturally means I had to get a complete dry fit picture!
I'm currently in the prime/sand cycle, so posts will likely catch up.
