Oops,

I fly in the chicago area, and currently the temps are in the upper 80s/ lower 90's.

I was turing the 13x7 at 9300 rpm on the flight days, and have recently had help tuning to turn the following:
13x7 = 10300
14x8 = 9000

I have not had a chance to fly at the new "tuned" levels, for the crosswind has been awful AND we have an event all weekend at our field.
