Semroc saturn 1B CP?

[matt38]

Hello all,

I substituted an Apogee Apollo capsule for the stock one and will be flying on an E-30. Can you folks help me with the CP on the Semroc Saturn 1B? I want to be safe for the first (and all!) launches.

The Semroc Rocsim file has the CP at 28.125 in from the tip of the capsule.
I built mine with a changeable motor mount, which added a little weight to the aft end and have the stock capsule. I've flown mine on 4 Cs, E15s and once on an F24 (see below).
So I think you will be OK.

And welcome to the Forum.

Thanks! Is it the tip of the capsule or tip of escape tower (5-6" difference)?
