I will achieve this by using integers instead of floating point variables, and by removing every unnecessary line of code.


But recently, I bought an Eachine QX90 (always wanted to adapt my own flight controller for a small brushed copter, but there was not enough time...). And it flies great. I however changed it a bit, here is my setup:
