Pixhawk mounting hole

I want to buy a pixhawk and mount it without the plastic shell to save weight. May I know if there’s anyone who has done it before and what is the hole distance and size. thx!

You can find the schematics here - https://pixhawk.org/modules/pixhawk
You should also consider the smaller pixracer. http://www.auav.co/product-p/xr-v1.htm

Hi, the scheme i found was in pdf files. im not very sure how to measure that. if there’s anyone who can help me do a quick measure of the mounting holes will be appreciated.
