Motor and Prop question.

[foamboardRCme]

Which generates more thrust? lower KV with a larger prop, or higher kv with a lower prop? something tells me it that it just sort of depends... but I've been wrong about that stuff quite a bit... so if there's an obvious answer, I'd really like to know it. Thanks guys.

Larger will always give more thrust.
Compare turbines - the bigger diameter of the fan the more thrust (and power).
