Does anyone out there know a lot about the engines used in model rocketry? What I am trying to do is this. Convert a large rockets engine from a three C6-3 cluster to a single D or E engine. I have already converted the engine holder to 24mm. What I need to know is will a D engine have enough thrust or will I need an E or larger. I am having a hard time finding this info on-line and I am sure it is there somewhere. Any help would be much appreciated.
