hello. I need buy a phantom shell , but I know there is a two version of shell for phantom 3 pro (one for old engines and new for new engines).

Tell me what version is this ?

I'm going to hazard a guess that is the old body style.  I ordered a spare a while back and got the new style and noticed DJI had placed a different sticker over the original (see photo).

FYI, the battery box is NOT included with the body.  You may need one of those as well. http://store.dji.com/product/phantom-3-center-board-compartment
