I built an Rsim model of the Estes Echostar and was wondering which CP calculation formula best suits this model, I would have thought the cardboard cutout method because of all the fins some of which are a little odd shaped, but according to this method the CP looks way to far forward than what I would think of as normal, Rsim and Barrowman methods seem to be way farther back than normal, I've attached a screenshot, what method would you think works for this rocket?
