I'm scratch building a rocket that will look like a pencil (minus bite marks, at least to start with)
The main body tube is a bt55, but i'm going to put a hexagonal wrap around it using yellow bristol board (might glue two layers of it together for strength. How does it affect CP when the body cross section is not round? Do you base things on the corner to corner width, side to side wdith, or an average of those or what?
