I built and launched a Big Daddy on a F35 this past weekend and almost immediately after burnout experienced a drag separation of the nose cone. Happy to report there was no damage to the rocket.
I had added about 2oz of nose weight to aid with stability with the larger motor. In addition, reading the thread linked below, I think leaving the aft centering ring out (I intend on adding a screw on motor retainer, I just didn’t have any with me) probably increased the base drag on the body of the rocket and the combination of the two led to the unintended separation.
My question, how much extra drag did leaving that centering ring off impart on the rocket? I added the nose weight thinking I’d need it for the F motor, but apparently the base drag of these stubby rockets aids stability. I’m curious now if I could just fly with an unweighted nose and leave the aft ring out permanently and still have stable flights on the F35.
