In the good ole days before installers you had 3 folders.... the one containing the aircraft, lets say "BAC 1-11" one called "Gauges" and one called "effects"
Gauages goes to gauges, efects goes to effects and the "BAC 1-11" folder goes into aircraft in FS9 or airplanes in FSX.... and changing the smoke is no more difficult than adding a repaint.... am I missing something?
... Oh yes, you need to copy the texture.cfg file from one of the default aircraft into each of the texture folders on the one your adding.
Still not that difficult... is it?
