It depends on the motor - rudes will work at lower RPM and be fine, Mercs need a bit of RPM. Props can be very different due to design at the same pitch, very aggressive props like Tempest- Mirage - Stilleto need to be much higher to work correctly - now you know why racers are always playing with props. 5000 depending on load is not too bad, that cruise is nice sounding, if you normally don't load it real heavy you could get away with that loaded, or try and raise it some.
