Just for grins, I will be posting a few pics while this build progresses (like many of my build threads, it will be sporadic and slow). Rocket is the "bare bones" kit from LOC Precision, the BB-81, sport scale Phoenix missile with a 75mm motor mount.
After unboxing and inventorying components, I decided to add another centering ring (thicker fore ring for recovery harness connection) and will be adding a compartment to the nosecone. So picked out two appropriate pieces from my stash of parts that I will be modifying for use in this kit.
First order of business was a few simulations in Rocksim and FinSim. The larger M's will push this smallish rocket to Mach 1.5 so needed to supplement the 1/4" ply fins. Here you see the eight fins with a layer of carbon fiber and vacuum bagged.
Then onto the airframes. Two wraps of 6 oz fiberglass on the booster, payload and switch band.
