My L2 certification rocket is a 88" long 3.9" diameter Quantum Tube Airframe. I am doing dual deployment using motor ejection for the drogue, and a perfectflilte stratologger altimeter for the main. I am planning to fly an Aerotech J350 for this certification launch and some larger motors thereafter. The rocket weighs about 8 lbs and Rocksim puts it at ~3500ft for apogee.
My concern lies in stability. Right now, my stability margin fully loaded is about 2.7. Is this ok as far as static margin goes for a rocket this size??, or should I add some weight to the aft to pull the stability margin down a bit. I have heard before that as long as static margin is between 2 and 4 you should be fine. However, I have also seen multiple forums online that say to design for about 1.5 stability margin.
Just wondering if you all could help.
This is my first post so thank you very much to anyone who responds
