F21-4W Econojet Motor (2)

|
These are Econojet F21-4W Composite Model Rocket Motors from AeroTech. Recommended for ages 16 years or older.
Fits all model rocket kits designed for black powder "E" motors.
The most technically advanced model rocket motor in the world, and uses the same propellant as America's space boosters.
White Lightning propellant type (W): A brilliant white flame, dense bright white exhaust, and a throaty roar are the hallmarks of this popular propellant. It's easy to track and exciting to watch! White
Lightning looks and sounds like actual sounding rockets and launch vehicles. White Lightning propellant achieves realistic simulation.
Pound for pound, this propellant delivers nearly 3 times the power of black powder.
Econojet composite model rocket motors allow you to fly larger rockets, heavier payloads, and achieve higher altitudes.
AeroTech's Copperhead igniters are different from other hobby rocket motor igniters both in form and function. (NEVER use Copperhead igniters in motor clusters)
