Estes 1/2A3-2T motors. This is a mini engine designed for light weight models. 
This pack contains 4 engines with 4 igniters and 4 plugs.
A great starter motor before you scale up to more noise and altitude!

The engine name is made up of 3 identifiers.
1/2A = The engines impulse, each letter doubles. The A motors have 2.5N/s of impulse. (B engines would have 5N/s and C engines 10N/s).
3 = The average thrust in newtons during the burn.
2 = The delay before the parachute ejection charge goes off. 0 means a booster stage, and P means a plugged motor with no ejection.
