Here is another rocket I built as I enjoy sticking big motors into Estes rockets. I laminated the body tube and balsa fins with one layer of 5.6 oz. carbon fiber, followed by a layer of 3.8 ounce S-glass. The fins are surface mounted (not TTW) with carbon fiber over the fillet. I put in a 38mm motor mount with four plywood centering rings. The nose cone is filled with two-part expanding foam and has a 1/4" eye bolt. I used an Aero Pack motor retainer for motor retention.
Dia: 2.6"; Length: 36.5"; Wt: 24 oz. (stock 6.0 oz); Motor (1): 38mm (stock 24mm)
