Oh nice, i really loved the strontium engine mate, i make mine cored almost all trough the grain, then it chuffs and caughs all time inflight;)

@skyisthelimitinc Thanks, I need to make the core thinner for more thrust. I'm preparing the tools...

[skyisthelimitinc]

@sparksnsky You mean deeper right? i make my str engine 20mm ID, 5mm nozzle and core, and 60mm long fuelgrain, cored all the way to the top plug

[sparksnsky]

@skyisthelimitinc Did you have a rapid & straight take off with this disign? Actually I was thinking of 4mm nozzle and core.

Nice! What comp was the red "chuffer" rocket? :P

And was it pressed or rammed? :)

THUMBS UP!

[sparksnsky]

@pyr0ph1L

Strontium Nitraten 55 %

Magnalium, -325 mesh 28%

PVC powder 10 %

Parlon 7 %

Vaseline (dissolved in laquer thinner) +2 %

I used a press. The core was 7mm but it seems that it must be less because it needs more thrust.

[pyr0ph1L]

@sparksnsky Yeah. Try a core with 5mm. If the end plug can hold back the power ot would be an awesome rocket fuel. :)
