Test of the Change Sun 70mm edf

I got this a few days ago and ran it up.
Details of the fan are here:

The set up: 6S 2200 50C with Mega 16/25/2E (kv-2300, Rm .015)

Amps: 35
Watts: 760
Thrust: 48 ounces
Grams/Watt: 1.79
I suspect the mediocre G/W reading is because the ESC was losing sync with the motor at full throttle a little.
Never the less, it's in the same ball park as others.
One important thing to note is that the motor used has a higher kv than the ARC 28-47-2 used for most testing.
For my goals, this is a perfect match of motor and EDF unit, as my goal is to get about mid 30 amps static, without a thrust tube. That way I get 900-1000 watts installed.
