I seem to remember that in v1 the engine smoke effect was generated automatically but I may be getting confused with another aircraft! In v1.1 I have to toggle the smoke on or off with the 'i' key. Am I right in thinking this is a change to the panel, or is it a setting on my system that I've changed inadvertantly?I generally use the kittyhawk aircraft but it is the same with the tinmouse.Regards, Ian

OK I see what happens now. It looks like the smoke is generated automatically when airborne when the engines are running at over a certain percentage of power. The 'i' key can be used to generate smoke at other times.Silly me :+
