This Package Contains Two F23-4FJ BlackMax Econojet Composite Model Rocket Motors from Aerotech. Recommended for Ages 16 Years or Older.
Econojet composite model rocket motors are the most technically advanced in the world. Econojet motors use the same propellant as America's space boosters. Pound for pound, this propellant delivers nearly three times the power of black powder used in other model rocket motors. Econojet composite model rocket motors allow you to fly larger rockets, heavier payloads, and achieve higher altitudes than ever before.
Used with single stage rockets. The "FJ" stands for Fast Black Jack. Recommended motor matrix: Initiator, HV Arcas, Strong Arm, and Wart-Hog. Primary use is for single stage rockets. Propellant effect is a dense, sooty black smoke. Burn time for this motor is 2.2 seconds. The average thrust of the motor is 5.2 pounds (23 Newtons); however, can peak at 11 pounds (48.7 Newtons). They each have a delay of 4 seconds. Compact motor comes with directions and performance specifications. Contains two 4-1/4" long copperhead igniters and elastic bands.
