Need a Part Name for These...(screenshot insdie)

I've been working on this F-4 for a few days now. I got the source file from FlightSim.com. I've just started animating it after tidying the model and scaling to the correct size. I've ran into a problem with what I believe are called 'elevons'. A quick look in the MakeMDL.doc showed that was such a thing. So I labeled them 'elevon0L' and 'elevon5R'. Well, knowing my luck...they didn't work. Can anyone give me the correct name to use?
Oh, yeah, here's the screenshot:

Thank you.
