With 3D printing there's really no point in not doing a model, it's not that expensive and tunnel time can be found in lots of places.

I've heard numbers as high as 100k (sorry can't for the life of me remember US or Euro based reporting to know, dollars, pounds or Euros) a DAY for wind tunnel time, add in employees needed on site and bits to test that's a LOT of money for that team to absorb.
