oops...sorry mate......thats what happens when I don't read properly! :roll:
For a stationary plane, you'll have to find the entry in your stationary.ini file.
the entry normally should look like this:
I_16TYPE18_______vehicles.planes.Plane$I_16TYPE18_______1
Double check that yours is the same, possibly the last bit from the $ sign onward is missing?
:wink:

Sorry mate, it is my fault
I had installed the I-16type18 before, but for the 4.09m I deleted it and forgot to delete the line in plane_ru， what strange is the plane still appear in the FMB.
Anyway, after delete the lines in plane_ru, stationary.ini and technics.ini, the "plane" gone :wink:
