1520 1Y 1600kv motor??

[Desert Rc]

So I have one of these in the box for Christmas but not allowed to open it. When I showed a picture to my wife she said "I bought a green can with wires coming out of it for $175??" I laughed and said it was a good deal.

So my question is to anyone that gotten one yet. I need the bolt pattern measurements and screw sizes so I can send them to "the dude" for a LST2 Mount so I can get it here for my chrsitmas build. Isnt the normal 15 series 25mm and m3 screw size...not m4?? I just wanted to make sure as I see the 6mm shaft on the 1717 was a surprise as I gather.
