New to GMAX... bit of a size issue

OOPS just found out how, so no need to reply unless you have a handy tip etc for a beginner :)
Hi all, I've just started experimenting with gmax, made a simple modle, and exported it to FS9.1 ok, but its HUGE. On export to mademdl gmax says that my modle is not stored in meters, is this the problem? If so, or otherwise how do I get my model to the right size? - I have the grid in gmax set to meters.
Thanks
