How to import the phantom 3 model in your scene
The model is composed of several parts.
For 2.8x, Use the file "DJI_phantom3_v2.8_BM_03". Link/append the collection "phantom_3".
For 2.7x, Use the file "DJI_phantom3_BlenderMarket_02". Everything is grouped under the name “phantom_full”. To link/append the model in your scene once in the browser of the blend search for “full” in the blend. You will find the group that contains everything double click on it or select it then import.
For both version you can also open the .blend file, select everything and copy/paste to your scene.
