I love the Estes Fat Boy so I decided to build a 1.5X upscale using the Performance Rocketry 4" fiberglass elliptical nose cone and PML QT. This will have a 38mm motor mount and TTW 3/16" birch plywood fins. I plan to fly it on small 38mm and 29mm motors. RockSim predicts about 1,100 ft on a PRO38 1 grain G if I can keep the weight under 3.5 lbs.
