I didn't recommend any specific factor of safety, and I generally do these calculations without them as they are kind of meaningless in this case.
For example, why design for 25% motor load with a FOS of 2, when you can call that 12.5% motor load.
It's a style preference, I just don't use FOS here (Although I use it a lot elsewhere).
AS for what % stall is okay, that's tough to say and depends on how often it's used and what motor you're using.
