I just checked the "Tricks of the Trade" thread, which is locked to prevent people from modifying it.
However, it was written in 2013 and was relevant and useful to users of the 1.28 series at that time.
However, in terms of EAW1.3 - UAW160 which use slot free planes it is irrelevant.

Fortunately there are almost 20 converted theatre folders in the UAW160 folder, and there are more than 2700 skin and flight model folders in the "Aircraft_Inventory" folder, with more on the way. Little, if anything, needs to be done by the average user, other than maybe using their favourite skins in plane-sets, and Ray is currently writing a tutorial as to how this can be done

Should the "Tricks of the Trade" thread be re-named to ""Tricks of the Trade - version 1.28" or something similar?
