I know the design works as I string tested it and have flown the design a half dozen times, but when I enter it in RockSim, it shows unstable.

Ring tails and RockSim have never quite gotten along together for several iterations of the program. RS shows a higher drag value, for one thing, and definitely doesn't calculate RTs the same as primary tubes. Jay Goemmer (CenturyGuy) might be able to pass along some comments, as this was an issue with his "Tau Zero" design. |
