I read the last page of the instructions, and "Parachute Powder" is just Talc, that will sorta look like smoke, but will be so light it won't really show up at very high flight or on a cloudy day. I guess just a gimmick to be like the real Nike Smoke. I also thought it had a 2nd port for the engine trailing smoke or you actually put in a "Smoke Bomb" from a firework store.

Thanks for the info.
