This is a re-draw of Bob Harrington's NIKE-X.
I utilized Chris Michielssen's 3-ply fold-over fin building technique and it worked out great.
This mini rocket uses a BT5 body tube, and a NC5-A nose cone from the Estes 003160 NC5 nose cone 5-pack.
EDIT: I built an Open Rocket file for the Mini Nike-X and it's attached.
With an Estes A10-3T, it has a stability of 1.38 cal., weighs 17.3g, CG is at the base of the triangular mid fins (17.7cm from the tip of the nose; CP is right at the motor block (19.6cm from the tip of the nose); it gets 28m/s off the rod, apogee at 118m, max velocity 71.3m/s (161 mph).
The second page of the PDF is build instructions and I think I covered everything.
I state in my instructions that it's streamer recovery, but I just added that. I'm guessing it's light enough for tumble recovery, but a 1" x 12" orange streamer really couldn't hurt and will aid in finding it if it manages to go into the weeds.
Give it a build and let me know how it all works out for you.
Feedback is appreciated.
