I recommend flying this on composite motors only. E26 or better. I managed to get a flight in on an Estes E12-4 and it flew, but it arched over and the chute ejection was on the down swing. Of course it landed high up in a tree. I managed to get it back after the 4th try and I'll have to fix the nosecone, but I'll never fly it on an E12 again.
You are expected to know how to balance a rocket for flight before building this. Printed with Polymaker LW-PLA it passes the "Swing Test" but that's not always a good indication. Open rocket says it needs weight in the nose (I printed mine hollow), so I added weight.
Use a standard Pringles can cut down to 200mm in length for the body for scale (They're about 224mm normally with the ends cut off).
I've included pieces for a 24mm and 29mm motor mount. For the 29mm mount you'll have to have your own retainer as there is not one in this design. Size the length of your 29mm motor tube accordingly.
I've oriented the fins the way
