Thanks JIMESTES and GPUTT33 I got the file to work, what a world of difference, I have the GP 232 with an OS 70 on it and it has been my favorite R/C plane ever, on it's 4th year and still flies great, EXACTLY like the standard one in the simm. But this 3D version is OUTSTANDING!!!!! I have never flown a plane with the radical control throws needed for hovering etc., what a blast! If I can only figure out how to get into the hover all will be well. Thanks guys, both of you were right on as far as loading the files, I must HOVER now, seeya.
