what does it tell me? If the static thrust of a 12x6 prop @ 12K RPM is 3.63kg? what do I need to know about this?
That this combination is suitable for a plane in the .40 to .60 size range depending upon what performance you expect.
An 8lb .60 plane will not have a better than 1:1 ratio with that.
However a 5-6lb .50 size plane will reach for the stars.
