The Maxi-Zip body tube length is actually sized to fit an 'E' engine. In order to use a 'D' engine, this adapter should be glued to the base of the BNC-50J nose cone before gluing it into to the body tube. Because there is no mention of using an 'E' engine in the Maxi-Zip, it is assumed that stability for this configuration has NOT been verified. Common 3 Launch Lugs 3/8" long 1 Pattern Sheet
