38 mm Diameter = 1.5" = 1 1/2" Delay times are 4, 8, 12 seconds and plugged, i.e.: H110-12 or H110-P Firestarter.^TM Delay times are 4, 8, 12 seconds, i.e.: I160-8FS. "ILP Method" = 1280J320-12-FS; 1280= total impulse Newton seconds, J= NAR letter class, 320= Average thrust Newtons, 12= delay time from burnout to ejection in seconds, FS= propellant read, Firestarter^TM Average thrust figures over 400 N available with a 16 second delay, i.e.: J440-16. All motors include 12 volt electrical igniter.
