Product Description
This Estes 'Sprint'-inspired fin unit, was intended for a mid-body ejection thus the extended length and longer shoulder as the joint. This unit represents the entire rear portion of the rocket; you supply the upper tube and nose cone! You can certainly make it a standard Sprint ( see Estes kit plans K-49 ). Both options will work! I included Larry Renger's ( Estes Industries) paper on the concept to help, should you be interested. http://www.spacemodeling.org/JimZ/eirp_72.htm
