The max rpm is rated at 5000 to 6000. Is it best to be at the top of that range, somewhere in the middle, at the bottom, or does it make no difference?
Set it up with a normal load and shoot for as close to 6000 as possible.
Keep in mind that "Prop it out" is a general term. There are a lot of ways to gain rpm without buying another prop. Usually dropping pitch means losing efficiency.
