I'm working on ways to make the OpenRocket stability calculations work better for stubby rockets. I've got some ideas of how to proceed, but I need real-world test data to validate the calculations.
So I'd like any examples of OpenRocket designs people have made that meet these criteria:
1. OpenRocket says the design is unstable if you don't do the "base drag hack" but says it's stable if you do.
2. the rocket has been built and flown, and is actually stable in flight
3. the Center of Gravity has been checked on the actual flight model and matches the location in the OpenRocket sim.
Cool stories about other situations where the base drag hack has resulted is cool/interesting/horrific things happening are also welcome, but I'm really hoping to get a collection of designs meeting these criteria so I can use them for software testing.
