HI Alex, there is an option in MoI that you can use for that currently. In MoI go to Options > Import/Export > FBX options and set the option for "FBX version" to something later than 2010/6.1 .

again thanks Michael works perfectly.

MOI seriously sharp pencil in the ol`TOOLKIT

Keep doing what your doing so well - Alex.

If you want you can set Apply Transformations in the import dialog. This will set the scale to zero and make the model, well correctly transformed.
I had been using OBJ but after Micheal's comment I thought I would give FBX another go, it works perfectly.

Its easy to get stuck in old work flow formats and miss new formats after using STL and OBJ for decades its time to move - a new FBX fanboy!
