You people have been such a good and quick resource. I need a good concept/formula to calculate a CP for a large project. What's a quick and dirty way and also the classic way?
Thank you The Rocketeer

Not the quickest method but if you use an old fashioned pencil it might get a little dirty. Otherwise if you like clean I'm sure a spreadsheet would help.

The quick and dirty way is to make a cardboard cut out of your rocket's silhouette. The centre of gravity of the cardboard cutout is the centre of pressure of your rocket. Roughly speaking.
The classic way is to use the Barrowman equation.

The quick and dirty way is to use VCP or the like. THe classic way is to use a slide rule or maybe an HP scientific calculator.

Why, back in my day, we had to use large stone cutouts of our models, and an abacus...

Lucky. All we had were piles of pebbles.
