So the story behind this rocket... My dad flies rockets, I fly rockets, both my kids fly rockets, my wife... doesn't fly rockets. But she does come to all the launches. So for a while I've been trying to convince her to help the kids with theirs, or build her own, or even let me build her one to fly so she doesn't have to sit all day and do nothing. So after years of repeated "you need a rocket"s my wife comes home one day and anounces she has a surprise for me. She has finally decided to get a rocket... tatoo. So being not so slow myself, and really actually liking her tatoo, I say "If I build one of those, will you fly it?"
My estimations convinced me it should fly fine with some reasonable nose weight. I mean hell I got a troll shaped piece of tagboard with long pink hair and grass and flowers to fly. So I have now modelled up her rocket, and I attempted to put it in Rocksim and Open Rocket and they both agree the center of pressure is 84 inches... in front of the nose. The cardboard cutout method in Rocksim does give an estimate pretty close to where I guest it would be.
So I would like to here from the experienced Mindsim users, approximately where do you think the CP is? For a idea of scale, from tip to the end of the fins is approx. 34in, the max diameter is approx. 12.5in and it has a 54mm motor mount.
