Hay Red..i told you, all of my ideas is only a key..we can go for any design with keeping the basic aspects in mind..an atomiser is, meant for, is a device, is used to covert a fluid, or gas in to minute particles, when it flows through this device..more clearly, to say, you can take an atomiser in a Carburettor of a Car...the petrol must be in its float chamber..and the tip of the atomiser will be dipped in that chamber,so when the intake pressure of the chamber increases as engine revvs up, the fuel will sucked in to the venturi, through the atomiser, while, the dense petrol is changed in to a fog like structure , means in to ATOMS....so it will be more light , while comparing to its mother fluid...so here we used an atomiser, to break the incoming air in to many little streams, so it can take up more smoke, without blowing off the stick...and sure you can place this unit as horizontal position, and can fix it anywhere in the craft, so you only to add a piece of aluminum just inside the bottle in under side...so it will blow smoke nicely...or you can fix the blower anywhere and can place the smoke unit some where...then you can connect these all ith silicon tubes...so nice...i will add all postings as i finishes my X bow tug...
