Hey all, I took some time off post 9/11 and am just starting to dip my toes back into rocketry. When I last made motors, I was exploring sugar. Have there been any significant advances in the field during my hiatus? What is the current state of art with sugar? Largest diameter sugar motor? Highest total impulse? Does anybody know the current sugar altitude record? Have there been any interesting/notable advances in the art? Ad Astra, Ray
