Just got back to working with these lately and have come up with a reliable motor. Im building a one pound motor/ 3/4inch by 6inch. at the "nozzle" end I use normal core burner tooling and the first scoop is BP with 5% oil added it makes a nice clean and hard end to the motor then ram as normal with your standard 70 15 10 B P mix that is ball milled for several hours. I ram until to the top of the core then switch to a very slow mix propellent to the top of the motor sealing with a normal clay plug. The motors are very loud and fly especially fast. IF you use a coarse charcoal in the slow mix part of the motor you get a interesting tail that shows up after most of the noise has departed. I often top them off with nice BP willow stars, it makes for a great rocket that is quick to put together.

Ive seen the guys site on anglefire and he is the one that got me started on this kick. His using WD-40 to slow down the fuel and make a good hard grain is a great working idea Ive tried it and it works super. I did hope to find others who are expermenting with it with the hope of speeding up my learning curve. And keeping the large booms from coming from the area of my yard down to a mininum. :D
