Because different hole spacing in circulation I have even uploaded the four most common. The total length is 117mm and usually you can install 6 inch props. The length from motor mount middle to first frame mount hole middle is 80mm. And in this version there are two motor mounting dimensions.

You can see in the picture which is A and which is B (frame mount dimensions M3)

Motor mount dimensions:
11,8mm - 16,2mm M2 (1804 1806)
15,8mm - 19,2mm M3 (2204 2206)
