Open Rocket also allows you to calculate CG and CP at different speeds. I was able to gain a 1 cal. static stability by putting 12 oz. of weight in the nose of a Wildman Gizmo, in addition to the DD cannon I had there as well. Any software that factors in aft drag should be able to be effective in simming a short fact rocket, whose stability is gained through aft drag. In the case of my Gizmo, under weather conditions similar to our launch site and a launch configuration into the wind that we normally take, the difference in altitude between OR simulated and Stratologger reported was only 4%. That is an acceptable margin of error.
