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, FirestarterTM Average thrust figures
over 400 N available with a 16 second delay, i.e.: J440-16. All motors include 12 volt electrical igniter.
