Change standard mixers

#1

Hi

I want to change the standard 8x mixer in pixhawk, specifically, change how thrust is distributed across the motors for pitch/roll (right now it seems pitch is achieved by speeding up motors 5+1 more than 3+7). Are there parameters that I can change or is this in the source code?

Thanks!
