Yup, I am new to what I plan to do, but I have played with
rockets (pre-fab kits) that were just 'follow the instructions'
and be a moron, but your rocket will fly.
I want to get away from that. I plan on rolling my own rocket
engines and using homemade black powder for the propellant.
I will start small and make solid core engines. Cored engines will
The fuel is not a problem. I just need to know the theory and ratios
to make a stick stabilized engine fly. You know, take engine, attach
stick, light fuse, see rocket fly type of thing. I know the center of
gravity should be above the center of thrust.
So for a given size and weight of engine, how long should the stick be?
I assume that the density of the stick has a factor in determining its
There has to be a 'rule of thumb' to use as a guide. Hey, this is a first
better rockets are in the future. Let me just get the engines right first.
Please do not reply to this post with "glue part A to part B, then glue A+B
to part C".
What if I want to change a proven design by reducing it or making it bigger
Maybe I want to make a 1" rocket or make a 5' rocket. There must be
something in common that applies to both sizes. Feel free to blast me if you
I am sure that this information exists somewhere. Include a link with the
