Performance Notes

The G78-4G is ideal for mid-power rockets in the 1-3 pound range. The 4-second delay works well for rockets reaching altitudes of 800-1,500 feet. The Mojave Green propellant provides the highest impulse density available in a 29mm motor, making it perfect for maximum altitude flights. Always verify motor compatibility with your rocket design and conduct ground tests before flight.
