I have the CP for the Star Orbiter at about 38.19" from front but I was wondering if the fins on the Vapor change the CP significantly?
I don't have a means of determining CP on a rocket at this point.

Anyone put out an Open Rocket model of either yet?

I looked the other day and came up dry.

Would be real simple to just change the fins and add or subtract weight. There virtually the same rocket with a different motor tube assembly, and the fins of course.

But yes I would suspect the CP will be quite different due to the fins difference of over all size and aspect ratios.

Really?

Granted I did not look that hard. Found one for the Star Orbiter but not the Vapor.

Thanks.
