Single Use, All-in-one
Solid Propellant Rocket Motors

With 12 volt electric ignitors.
Just apply a 1/2" or 3/4" wide masking tape
thrust ring to the nozzle end of the casing.




40E25 motors are the same diameter as the popular Estes 16.2D12 motors.
The ILP method (40E25) 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 40 N-s power and 25N
thrust burns for 40/25=1.6 seconds.


Many motors are made from the same size casing.

Delay times are 4, 8, 12 seconds and plugged, i.e.: E50-8 or E50-P.
"ILP Method" = 60F36-8-STD; 60= total impulse Newton seconds,
F= NAR letter class, 36= Average thrust Newtons, 8= delay time
from burnout to ejection in seconds, STD= propellant read, Standard.
A capital letter denotes nearly full NAR letter class power and lower
case denotes partial NAR letter class power ie. 80F50-4 or 60f36-4.
All motors include 12 volt electrical ignitor.

| Propellant Grain Geometries |
Most motors are BATES coreburners,
but the 24mm E8 and f9 are cored endburners.
Endburners and high thrust motors use Fast propellant
and medium thrust motors use Standard propellant.
