What is a Berthasaurapod, you ask? Excellent question. In this case, its a modified Big Bertha type design, with SRB pods added. Why Berthasaurapod? I don't know, it was the first thing that popped into my head at the time, and it amused me. Anyway, as noted, the design is an evolution of the Bertha configuration. I was going for something sort of sci-fi. I am not using a Big Bertha kit as a basis, and no actual BB kit parts are used here, that was just the starting point for the Rocksim file. What I have retained from the original BB is the nose cone (by that, I mean the original BNC-60L, not the later PNC-60MS), the tube type and the overall length. But since the fins are shorter, the tube is longer than the 18" part in the kit. Anyway, this is what it will look like:
This is what I'm starting with:
The pods are 5" segments of #7 tube, and with the cone/nozzle sets, were purchased from Semroc. I've got a BNC-60L, from BMS, a boat tail from an Astron Sprint XL, a cut-to-length piece of BT60, BT50, centering rings, motor block, retaining hook, and 3/32" thick basswood. You can see the fin pattern print out from Rocksim, although there is another (not shown) for the small strake fins.
