- XNova 2204(2205) 2300kv
Even though this motor isn't a very common motor, I've had a TON of requests for the XNova 2204 (2205) 2300kv. Here it finally is, thanks to a friendly donor! Once I've done the full bank of motors, I'll do a document sumarizing the direct comparisons.

As I've never had any previous experience with XNova as a brand I wasn't sure what to expect here. The motors are very solidly built, on par in material and weight with the Emax behemoth, weighing in at 30g. The XNova has an external prop adapter that fastens by four screws to the top of the motor, rather than a direct prop mount like many of the other motors in the series. I've seen reports of the threads stripping form these, but all four screws went in nice and tight on mine with no problems. Machining on the motor was very nice and the tolerances were very tight, rivalling the Emax. Bearings were extermely smooth and very solid. The magnets appear to be a slightly lower strength than the emax, but other than that the two motors are very comparable. Probably the biggest thing to note is that the stator size on these is definitely 2205, rather than the 2204 on the label. I'm not sure why companies feel the need to do that. That being said, the quality on this motor is very high, and everything else seems to be in line.
Now on to the bench results!
There weren't any real surprises here. The motor did very well. If I had tested it 3 months ago I would have been blown away. As it is, it's performance was nothing to laugh at. It squeaked in just below the Emax RS 2300kv in terms of thrust and RPM output across the board. Top thrust output was just over 1270 grams, and it perfromed equally well acros the range of props. Basically the only difference between these two is magnet strength, everything else is very much on par. Everything considered this motor is a very solid performer, though the weight and expense may be an issue for some buyers.
