US Rockets Expendable Motors

20D12 motors which are the same size as popular Estes 16.2D12 motors.
The ILP method (20D12) describes a motor with power in Newton-seconds,
the NAR letter class, and the average thrust in Newtons. There are
4.45 Newtons per pound and a motor with 20 N-s power and 12N
thrust burns for 20/12=1.67 seconds.

Many motors are made from the same size casing.

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.
