This is my first firing of a finocyl core geometry. The combustion chamber pressure went much higher than expected at startup, and the motor had a lot of erosive burning. My chamber pressure transducer was flatlined for the beginning of the burn, so I do not have accurate data on that. The thrust curve was quite regressive.
