Regard the vertical take off, your model in Oxygen 2 probably inst facing the right way. Make sure the front of the plane is the front on the "front view". May help to go to View > Solid Fill Faces.
Also in your animation in your model.cfg you are using the source "rotorH" which means "Rotor Horizontal". Try using "rotorV" also have a look at http://community.bistudio.com/wiki/Model_Config#Animation_sources :) If you need any more help add me on skype "mailrage".
