I'm planning out a mod of a Partizon kit, with an extra nose cone converted to a boat tail. I'm having a couple issues:
1) I'd like to cut off the tip of the nose cone such that a 38-29mm centering ring just fits in the back (I'm going to leave a bit of 29mm motor tube hanging out the back to install a screw on motor retainer).
2) I want to extend the fins onto the cone, and need to know the profile.
So for both of these, I need a precise profile of length vs. diameter for the cone. Is there a good free calculator and/or published profile somewhere? I have OpenRocket but not RockSim.
