I confess, that I tend to build kits, not design new rockets. So I do not spend much time on Center of Pressure vs Center of Gravity relationships. However, I do normally conduct the old 'string test' (attaching a string to the rocket at the CG, w/ motor installed, and swinging it around).Sorry for being vague, trying to work quickly on my phone.
I was just musing about how the CP of the open-framed rocket is a bit of a mystery (to me at least), which makes me wonder whether the skinned rocket will be more or less stable.
It might be totally fine, I just realized that the answer isn’t necessarily obvious (again, to me). However, the skinned rocket would be easy to model in OR or Rocksim to find CP if desired. The unskinned rocket... who knows.
When initially building the Mega Rebel, I was surprised that no CG was listed. When I contacted the Rockitarium (kit seller/designer), they stated that the Mega Rebel had been an act of trial and error. This was why I was careful to add CG info (that I obtained) during my Mega Rebel build.
So, living in the middle of nowhere in northeast Arkansas can have its advantages.
