That reminds me. Another DECAP is plugged at the top and has 9 seconds of smoke. Used in "extra" engines in clusters.
Colored smoke is something we are looking at. Orange has always been my favorite, but it leaves bad stains from the dye. Manufacturability and repeatability is also a problem. Getting the delay correct with a reasonable amount of smoke is our primary design goal. We used hexachlorethane in the 60's which made volumes of smoke, but it was volatile and the delay time decreased with age. We will probably start out with the a more conventional delay.
