'Zilla and I have several FSI motors marked CS-2-9. The labels are the
usual NAR symbol, safety and contest certified markings, MFG code 2 81 72.
Case and nozzle look like an F100. We dug a hole and fired one wqith a
quick-burst igniter dropped half-way down the core and it even looked like
an F100 burn. What are these critters?
