My original mini fat boy that uses the mini engine is a pretty boring 250' low level flight, so i decided to build another one which use the larger A,B,C 18mm engines. Went to hobby lobby and purchased the baby bertha kit ($7.98 dollars) and converted it to mini fat boy by cutting the body tube shorter and trimming back of nose cone for more recovery room. Also had to cut out fins to match mini fat boy. This new rocket flies perfectly strait and lots higher. Compaired to mini engines the larger engines are lots more fun. Rocket flies slightly higher using A engines, Twice as high using B engines and out of sight using C engines.
I super glued a piece of 1/8" plywood in nose cone to tie shock cord to. Gorilla mounting putty (4.5 squares) was applied to inside tip of nose cone using 3/8" dowel rod. With heavier/larger Estes C65 engine installed CG is 2 13/16" measured from bottom tube edge.
