I also have a question about FMB. How do you raise objects into the air, for example in the air race server I have seen lights on top of the factory smoke stacks that they use for the course.

You place your object -- click enter now this is the tricky part.
Press and hold F4+left click mouse and push away from you. The object will rise.
If you want more at the same level press the INSERT key the number of time you want say 4 --
press it three times as you already have one there.
