After playing +2000h of ksp I'm flirting with the idea of making my own real life SRB rocket. A small version off course...
I found some cool instructables online which explain how you can make solid rocket fuel using sugar, potasium nitrate and a pinch of iron oxide.
The isp is not really high (100-130 ) but heck... it would be cool to get a small craft of the ground.
Does anybody have any experience with building real life amature rockets?
Do you have any kerbally design tips?
