This is the 2205 mid-KV motor in the X4Pro line of motors, the second motor in the line from FPVAces.
This is the littlest brother of the 2207 2350kv motor that was tested a few weeks ago. Build quality and construction is essentially identical, except for the smaller stator size. The motor is still a bit on the heavy side for a 2205, coming in at 30g, but not bad considering the hefty nature of the larger motors in the series.
As with the other X4Pro motors, this motor uses N50SH magnets instead of the common N52H magnets in the typical modern powerhouses. That impacts the results a bit, bringing this motor in a bit lower than the modern power-house 2205s. Results here are pretty much directly on par with the other N50 class motors that have been tested, clearing 1kg on most of the heavier 5" props, and just hitting 1300g on the 6x4. Current draw on the top end is quite managable as a result, but the top end response is reduced proportionately as well. This particular motor does gain back a bit of ground on the heavier props thanks to an extra 0.5mm on the stator height, so it remains quite a decent midrange performer.
