these are completely different values (so you can't use them) as the stability ones are used to level the quad, position values are used to tell it the direction to go
use default values as starting point ;)
I don't think so. The PID values used for keeping your quad level and those used for position hold relate to two different processes. They receive their data from different sensors and effect their output in different ways.
On my quad, the PID values I use for stabilisation are between 0.1 and 3, where the position hold values are between 0.001 and 0.01. I'd recommend starting with the default values and working from there.
