I got a pair of short conical PNC-20 nose cones in the Estes Designer's kit--perfect for SRBs. Here is a tube fin rocket that uses them.
I decided to duct the ejection charge into the SRBs--I plan to
hold the parachutes in place for nose cone ejection with some centering rings just above the ports.
A Rocsim simulation indicates that some nose weight is needed for C engines.
I plan to put nozzles on the SRBs.
