29mm Diameter = 1.125" = 1 1/8"* 1.4s Limit - † DOT Limit - ‡ FAA Limit. Delay times are 4, 8 seconds and plugged, i.e.: F20-8 or F20-P. FirestarterTM delay times are 4, 8 seconds, i.e.: G45-4FS. "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, FirestarterTM. Average thrust figures over 50 N available with a 12 second delay, i.e.: G60-12. All motors include 12 volt electrical igniter.
