An hour later... Dismal...
Is all I can say.
The EDF starts out with 1160 grams here
in free air. Note - All these tests are without any cheater inlet... just the scale inlet.
Test 1 - 509 grams
This test was with the wing removed and the nose off. This lets in the maximum air even if the insides are cluttered with equipment... no internal ducting.
Test 2 - 410 grams
This test was with the wing on, but the nose off.

Test 3 - 130 grams
This test was with the wing and nose on.

Not that I had any doubts ahead of time, but I think that is conclusive evidence that a cheater inlet is mandatory!
