dangerousamateur Posted June 22, 2014 Share Posted June 22, 2014 2 -3 seconds per 3/4". depends on how well you mix the comp :-)That seems very fast to me. My blackpowder fuel for coreburners burns about that fast. Can that be true? Does the glitter pass through the nozzle or does the slag stay inside?

nater Posted June 22, 2014 Share Posted June 22, 2014 According to TR, the Winokour 39J does pass through the nozzle better than other glitters. He says his own D1 is not the best choice for rockets. Link to comment Share on other sites More sharing options...
dagabu Posted June 22, 2014 Share Posted June 22, 2014 I second that, D1 often looks spotty at altitude while 39J looks consistent. Link to comment Share on other sites More sharing options...
