Hi Athro.......this often happens when using fs8 models in fs9.........when you first selected the a/c you probably got a warning about incompatibility and a Yes or No option...you should have clicked NO but probably as many do clicked YES.
If this is so then open the FS9.cfg file and look for the section ...
[FrameCallNoWarn]
EB52V3=0
.....if you have the same plane as mine it will have the entry for the EB52V3=0 as shown.........change the 0 to 1....EB52V3=1 this will give you the U/C.
If that isn't the plane then look for yours in the list..........commoner

BTW....I have EB52_v3.zip the 4 engine version...there is the 8 engine version on the same page here on SimV.
