DonCopal Posted November 15, 2015 Posted November 15, 2015 As a delay mixture, I usually use some Veline Star mix (red or blue) and it works great if that's what you wanted to know.
schroedinger Posted November 16, 2015 Posted November 16, 2015 In a eocket you just press it in over the spindle. You can use e.g. win 39, zinc stars, c6, c8, tt, whistle. So basically every glitter, flitter or color comp that can be ignited by the rocket fuel and burns at a constant speed. If you use nl bulkhead it needs to burn fast enough, so that it can retain the pressure on itself. If you would use glusatz (just as an extreme example) your delay woulb be only 2 mm thick and you can be sure it would blow through.
