The only time I get smoke is on engine start. I looked at the 2D, and noticed a 'smoke" switch, but it did not appear operational in the "Gmaxflight" model (the one with the blue and grey paint job). Try toggling that switch in the ones you are having problems with (it's way down at the bottem, lower right, on the 2D panel You can't even read it's purpose until you mouse over it).
I did notice that on the military models, if you start with engines on, and have the throttle full on, it belches black and grey smoke and the roters never spin up until you back the throttle down.
