Our wind tunnel model is coming along, with one of the aluminum wings shown above. This is a nearly finished surface, with an unfinished surface shown below. The wind tunnel model is being done as a triple check on the low-speed flight characteristics of the new box tail.

The body of the wind tunnel model is being made from white oak, as that is a commonly used material for tunnel models. If we made it out of aluminum, the model would be very heavy and hard to handle. As it is, the vehicle will probably take two people to mount in the wind tunnel for testing. Shown below is a section of the ducted fan area still mounted on the automated milling machine. Lots of sawdust!
