So this is the first rocket I have built not from a kit. I used all PML components. .188 fins and a 75mm engine mount I used mostly spare tubing I had laying around plus a new section for the fin can. It's 3.9 qt reinforced with a phenolic coupler throughout the entire length. Hopefully this will give the qt enough strength. To withstand supersonic flight. I epoxy filleted the fins inside and out and then foamed the fin can. Im using a 1/2 tubular Kevlar shock cord and a giant leap tac 60 inch main plus a 24 in tac drouge. I still need to assemble the avionics sled and bay. I'm planning on using a pair of rrc2 altimeters plus a simple GPS transmitter. Hopefully she will be a good rocket
