2010 October 03 - Speed Run Minimize

I have made quite a number of these runs to test various changes but have never documented them here as I did not feel my results were "good".  I am now using the "speed run" measuring method from Paul Lipps as published in Contact! Magazine.  I feel is a very "solid" method that produces repeatable results.

At the time of the test, the wind aloft forecast for 9,000' was 260 @10 and +13 degrees.  The station data for ABQ was 46 degrees, 42 degree dewpoint, and barometer at 30.34.

Run Heading: 090-270
At Run-up: 4829’, 30.26”(?), BAR 25.3”, 64 OAT
Speeds in knots.
Temperature in degree F.
Temp1: Thermocouple on right side coolant outlet port.
Temp2: Thermocouple on coolant tube before radiator inlet
Temp3: Thermocouple on coolant tube after radiator outlet

Flight2 OAT sensor: Left canard root (outside of fuselage)
EM3 OAT sensor: Right canard root (outside of fuselage)

**Flight included a large cardboard extension to the coolant duct outlet. This was in an attempt to get more air flowing thru ducting and colder coolant temps.
