Terex-Demag AC500 improved 1.3

it works great! ive been waiting for a Heavy duty mobile crane for ages
So i was getting this crane hoping that id be able to lift things with it but It seems that when i try to use it It is very slow to extend And one of the controls for it is Alt F4 You know what that does

And i cant seem to rotate it Other then that its great But would be nice if it could be fixed
This was a really great crane in the past; now, it's even better. Thanks for giving this crane a slight aesthetic rebirth!
