I was able to get this motor from a friendly donor to test.  It's not brand new, but it still did VERY well for a true 2204 motor. Once I've done the full bank of motors, I'll do a document sumarizing the direct comparisons.

Summary

There's a few intersting things about this moto that I've not seen before on others.  The design is totally unique, unlike any of the other motors I've tested.  The shaft is 5mm hollow tube with a 3.5mm inner diameter.  As a result the bearings and circ-clip are a good deal larger than any of the other motors I've tested.  I'm not sure how that impacts long term durability, but it is an interesting note.  Other than that machining is good, and the windings look fine.  No other suprises. The stator height measured at exactly 2204 as well.  Balancing mud is present in the bell, so they've been dynmically balanced.  The bearings feld smooth when spun by hand with no prop, but there was some rattling under power at certain RPMs, as well as when spun fast by hand with the prop on. However, please note this is a used second-hand motor, and I don't know much about it's history before I got it for testing.

Now on to the bench results!

Test Results

I was extremely surprised by this motor.  It performed extremely well on the bench.  It performed very similar to the RotorGeeks 2204 2300kv motor, and almost cought up with the lower power 2205 motors.  It and the Rotorgeeks were the only 2204 motors I've tested so far to break 1kg thrust.  It definitely started getting hot, with a strong smell of resin on the last two props (5x4.6BN and 6x4) but unloaded in the air I expect it to handle even the heavier props fairly well.  Overall for a true 2204 motor it did extremely well.
