I am determined to make the biggest Deuce's Wild so far! I'm going to buy a Deuce kit and then buy some BT-60 body tubes. A normal Deuce is around 21 3/8", I'm planning to make one that is either 39 1/8", 57 1/8", or if I am really feeling crazy when I build this thing, a 75 1/8" Deuce. What are the limitations for the Deuce? What is the tallest I can go and still launch it on 2 C engines? And more importantly where does the height begin to effect the safety of the rocket? Oh yeah, I am also ordering a Richter Recker, so my next two projects are going to have to be built on the floor rather than my work table.
