In my area they have a couple packs of the sonic starters but no composites,
What are composites, and how do they differ from Black Powder motors?
Motors with much higher specific impulse propellant than BP -- therefore much lighter for the same power. Also considerably more expensive.
Composite propellant usually requires different ignition systems than BP motors.
When Estes came out with the Pro Series II E2X line and the BP motors, HL dropped the original Pro Series II and AP motors. Don't know why. With the 40% off coupon, it was a great way to get cheap AP motors with no HAZMAT!
