I'm not very familiar with how smoke systems work. I have an Pulse Xt40 woth a OS .46 and stock P-Box muffler. Can I get a inexpensive smoke pump without having to switch mufflers and without having to mod anything too much? is it even practical ?

I was looking around Tower and saw the Macs Smoke system. here is the link http://www2.towerhobbies.com/cgi-bin...?&I=LXZ674&P=7 . I'm sure it probably wont create dense smoke like some of the other systems, but would it work ok ? From what I figure, i just have to tap the muffler and add a servo right?
