3/16" (5 mm) diameter two-piece launch rod - can be used in the 2215 Porta-Pad II or 2238 Porta-Pad E launch pad Necessary for most larger Estes rockets that are powered by C11, D, and E Engines Extra strength and stiffness for heavier rockets and higher power motors Length: 18" Includes safety cap Going big? You might need a stronger launch rod, like this 3/16 diameter rod built for heavier rockets and higher power motors. It attaches to the launch pad, and your Estes rocket simply slides over the rod using the launch lugs attached to the rocket. As the rocket launches, it quickly gains enough speed to fly with stability, and then leaves the launch rod. That requires roughly 30mph, and this length is perfect to accelerate most Estes rockets to that speed for most larger rockets that are powered by C11, D and E Engines. Also works great when used as an alignment tool on model rockets that require two launch lugs. Can be used in the 2215 Porta-Pad II or 2238 Porta-Pad E launch pad.
