Here is how you do it...


Edit the plane to enter the "Airplane Editor".


Next enable the "Advanced" functions by clicking on Options at the top of the editor window.

With the Options menu open click on "Display".

In the "Display" menu click on "Advanced".

Now the editor displays all available properties for component parts of the plane...


To add smoke click once on the engine component in the lower left window.

That will highlight whatever it is called...

Now right click on that same lower left entry and select "Add" from the pop-up menu.

In the menu that appears, select "smoke".

Now you can position the origination point of the smoke by first selecting the smoke component on the left, and clicking on "Location in Parent" on the lower right.

Select X to move the smoke laterally ( along the wing, out from the fuselage ), and scroll the figures with the mouse wheel or key in values.
Select Y to move the smoke along the fuselage ( aft or forward ) and again use the scroll wheel.
Select Z to move the smoke up or down.

Make sure that you assign "Smoke On/Off" servo to something ( normally a switch ) and "smoke quantity servo" to the throttle servo... and you are done.

You can then save the file and/or play with the colors, smoke duration and quantity.

The better your video card, the better the smoke effects get.
