Here's a pic using the original max 6/7/8 exporter: The original exporter rotated all of the bones -90 degrees, generated a bad scene root which JKA cannot use and did not output any basepose (bindpose/skinpose) data which is why the model is all over the place. Now using our new exporter: Exported bones are fixed how they should be, it generates a proper scene root called model_root and outputs correct basepose (bindpose/skinpose) data.
