29mm Diameter = 1.125" = 1 1/8". Delay times
are 4, 8 seconds and plugged, i.e.: F20-8 or F20-P. Firestarter TM delay times are 4, 8
seconds, i.e.: H120-12FS. "ILP Method" = 310H120-12-FS; 310= total impulse Newton
seconds, H= NAR letter class, 120= Average thrust Newtons, 12=delay time from burnout
to ejection in seconds, FS= propellant read, Firestarter TM. Average thrust figures over
50 N available with a 12 second delay, i.e.: G60-12. All motors include 12 volt
electrical igniter.

Testimonials and Product usage
U.S. Rockets Firestarter propellant

Your Firestarters are still by far the best sparky motors I have ever had the pleasure to use, especially the bigger ones.

Certified with a U.S. Rockets H160. Didn't need no stinkin instructions. The flight was great, as were several additional. The motor worked great in clusters also, as did the H120.

FireStarters were cool, but I never bought any. I heard a lot of "what the hell was that!" on the range.
