Pack contains igniters, igniter plugs, and recovery wadding. Letter indicates engines maximum total impulse: A=2.5 N-sec, B=5 N-sec, C=10 N-sec. First number indicates engines average thrust in Newtons. Second number is the delay time in seconds between end of thrust and start of ejection charge. Note: Rocket engines contain flammable solid material; there is an additional hazardous shipping charge for each shipment.

Each pack contains igniters, igniter plugs, and recovery wadding. Letter indicates engine's maximum total impulse (equal to the engine's thrust in Newtons times the length of engine burn in seconds): A=2.5 N-sec, B=5 N-sec, C=10 N-sec. First number indicates engine's average thrust in Newtons. Second number is the delay time in seconds between end of thrust and start of ejection charge. For example, an A6-4 engine has the same thrust and delay time as a B6-4 engine but burns only half as long.

Note: Rocket engines contain flammable solid material; each shipment has an additional hazardous shipping charge.
