I like it a lot, Craig.

At first I thought it was just larger forward and aft sections joined by a thinner midsection. That in itself would make me like it, and I probably won't even attempt to build it with the 5 (!!!) smaller gas ducting tubes between the forward and aft sections. Maybe I'll modify it with a single small tube to duct the gases.

Since I don't have Rocksim, I opened the .rkt file in OpenRocket 1.1.0, and it told me it was ignoring the spill hole in the parachute (did you use one?). However, it also shows five 1/4" tubes overlaid on one another at the model's centerline between the forward and aft sections, and it doesn't show a motor mount at all. So I added a motor mount, thrust block, centering rings, and motor clip (mass object). I haven't looked into the parts in much detail, so I don't know what else it might have missed or screwed up.

Using a C6-5, max. altitude in OpenRocket 1.1.0 was ~575 ft.
