I've been working on a live firing gun for my HL tiger. Before starting on the gun, I was playing around with smokers too, but I just saw one that uses "'fog juice" and looked good. It's the same one that Saxondog has. Just got it and slapped it into the Tiger. It really smokes well. Install was easy - plugged into the smoker plug on the board. Also had to solder two wires to a motor to get proportional smoke. Clip shows the smoker in the back yard in a pretty stiff breeze late this aftenoon. There's no barrel on the tiger - the whole tank is still being rebuilt. My first tank, so I can't judge if this a too little, too much or just right smoke.
