This was a madcow Little John paper rocket, 38mm motor. After a number of flights, amputations and application of fiberglass to the top for repairs, I want to convert it to a dual deployment rocket to practice so I can get the hang of electronics and dual deployment before I buy a large rocket. The rocksim file has these changes and see my questions.
-Started with the original madcow rocksim file.
-Added a coupler with bulkheads for altimeter. Copied the specs from another madcow design for these parts.
-Added an 18" section on the nosecone side. Copied the specs from another madcow design for this
-I changed the mass to the current weight, plus an estimation of the new parts, no motor.
-I have not calculated in the hardware and sled/electronics yet to the mass.
the modified rocksim file is attached
Questions:
Anything obviously wrong, like the length and the CG to CP? Is TOO over-stable bad.
Is my general methodology correct in how I am approaching this?
thanks in advance for any advice.
