The Estes Alpha III Launch Set (part #EST1427) is a great set for scouts in a short time. It’s a starter set so it includes all of the launch supplies you need. For the other rockets, you can buy a Alpha III bulk pack (EST1751), which will provide savings by purchasing in bulk. In addition, you can purchase the recommended A8-3 bulk motors (EST1781) which includes engines, recovery wadding and igniters. Don’t forget that you will also need wood glue (ELG7000) and plastic cement (TES3516) to complete the model rocket.
What is the igniter in a model rocket used for?
An igniter is a device used to ignite a rocket engine. An igniter element is a strip of resistance wire with a coating of pyrotechnic material on it. In the system it performs like a resistor in an electrical circuit. As electricity passes through micro-clips connected to the igniter, the igniter begins to glow and give off heat. The pyrotechnic material coating is ignited and is the last step in the ignition. Igniters must be installed so that the coating is touching the dark-colored propellant grain. If the igniter is not touching the grain, this could cause a misfire.
