Quest Aerospace makes a reliable rocket motor that is great for most rocket kits. They are particularly great if you are on a tight budget!
These are an easy-to-ignite black-powder propellant rocket engine. They are all the standard 18mm diameter motors that are 2-3/4 inches long - which are the same size as the "regular-size" Estes rocket engines. The big difference is that they are lower in price. They will loft your rockets just as high, and just as fast as the Estes motors. Since they are black powder, they produce lots of thick, puffy grey smoke - making them easy to follow up into the air.
All the motors come three to a package. They the new
Quest Q2 igniters, which can be purchased separately.
