I’m having trouble with stability in the sim. The booster is built on shipping tubing and turned out relatively heavy. Even with the electronics and batteries in the Recruit, it’s not long enough to get the weight forward enough. Without extra weight in the Terrier interstage, it’s simming at Cp=Cg.

So what I’m asking is when is it appropriate to use the base drag correction hack. The booster is 24” long and 5.75” diameter. So about 4:1. But the whole stack is much longer.

So is it reasonable to use the sim hack, or not?
