I am in the process of building a Madcow 4" Phoenix and plan to launch it on a CTI J330 for my L2 attempt.
The instructions state that I should drill a small 1/8" hole in the chute compartment to allow venting. I have also read/heard that I should use shear pins. I am assuming that I should do one or the other, but I am curious what the experienced guys think. Simulations show the launch reaching just over 4060 feet with a max speed of 565 mph.
The other question that I have is about who to certify with. I am both Tripoli and NAR and so is my club. Should I go for both or just one of them? Is there an advantage to certifying with one over the other?
Thanks for your help!
