Post Flight Times: Engine: 14.7, Total: 17.1
Flight Time: 2.7
Oil Measured 6.75 (HOT) after the flight, but measured 6.0 (COLD) before flight #12.
This flight consisted almost entirely of climb performance testing.
First series of tests were done 2400 RPM and 2nd series of tests were done 2500 RPM.
Climbs were from approximately 2000 to 6500. Stable data was 2500 to 6500.
For each climb test used the trim to set the airspeed. All data was recorded and later entered into a spreadsheet.

It was evident that there was better performance in the climb at lower altitudes in the beginning of the climb. IAS was taken as an eyeball average of the data mid climb around 4000 feet.
Need to find and record OAT here.
