Did you design it for 24mm or 29mm E motors ?I could... If I knew the mass of an expended "E" casing. Also... for my own personal interest. What is the wall diameter of an E casing?
On a 24mm case ( C11, D12, E9, E12 ), an "educated guess" would be .125" wall thickness ( without measuring it ).
Something else to consider . . . With an expended case, the mass of the clay nozzle will cause more weight to be located further aft, rather than simply treating the expended casing as a constant density "mass object" in the sim.
