D9 motors with a 7 second delay, for upper stages in multi-stage rockets or for very light rockets, where a shorter delay would cause an early parachute deployment.

Same size of standard "C" motors but much more thrust - 9 N instead of 6 N (30% more!) - and more burn time (2.1s !). This is a full 20 Ns D motor in the size of a C !

Use them in your rockets for B or C motors to see them go much much higher! 

Suitable for Estes, Quest and any other brand kit designed for 18 mm motors.
Package includes 6 Motors. 

Includes 6 high reliability electrical starters for 100% safe starts!
