Hey guys, most smoke pumps weigh 4 or more ounces plus an additional battery can bring the total weight up to 8oz or more. The harris pump will only add 2 oz + the wieght of the extra tank and lines so your total system weight is around 4 oz. The fluid does add extra weight but it gets pumped out during flight.
Heh... add in a typical 10+oz smoke tank and that weight at take off is a big factor.
I consider 1.6lbs+ a reasonable estimate of how much weight a smoke system adds in, and this is before you deal with heating coils or a smoke muffler, etc.
On a larger plane this has a lesser impact. On my Skybolt and Ultimate 1.20 I ended up removing the smoke system due to the additional weight....
