Bad 3d model i take!!!!!

As noted at the bottom of the preview, it is a low resolution preview. I you want the full resolution download the OBJ/MTL/JPG fileset and open it Meshlab. 

The preview is limited to about 100,000 faces since we are trying to make it easy to view in a web browser window. The model might be 10s of millions of faces. The trees in your model eat through the 100k faces pretty quickly... 

Using a newer aircraft is the best thing to do. The Phantom 3 is not the highest quality camera available these days...
