Performance Notes

The G53-7FJ is ideal for mid-power rockets in the 1.5-3 pound range. The 7-second delay works well for rockets reaching altitudes of 1,000-1,800 feet. The Black Max propellant produces a distinctive black exhaust plume with dense tracking smoke, making it easy to follow your rocket throughout its flight. The propellant is U.S. mailable, eliminating hazmat shipping fees. Always verify motor compatibility with your rocket design and conduct ground tests before flight.
