Completed fuel flow test after much preparation. Picked a fantastic day to do the fuel test since it was only 101 degrees outside today! And digging the hole forr the nose down test was not much fun. However we did 4 tests in all: level, nose up, nose down and unuseable fuel remaining. Photo 1 shows plane in 16 degree nose down position. Photo 2 shows same but from right side of plane. It took some time to get the fuel pumps primed but once they were primed everything work out. All the test results were very positive so I now know that the pumps will provide sufficient fuel to engine in nose high and low attitudes. My unuseable flow worked out to be mere ounces when level and about 1.75 gallons for nose high and low. Next up will be aileron rigging.
