AOKFly has sent in a few motors, and I have always been extremely impressed with the build quality and machining on their motors. This new motor from them is no exception. They've updated the design of their original FR2205 motor with a plethora of new features. The Fire Pheonix is much lower profile, has thick single wire winds, arc magnets, and uses a machined hollow shaft design with a retaining screw, all while losing about a gram of weight over the previous design at 28g. Overall some good improvements here. I have a few minor gripes. The shaft retaining screw is unfortunately very soft metal and the loctite compound they use is very strong, so I wasn't able to remove the bell to confirm stator size. The head of the screw stripped out long before the loctite gave. I've had this problem on enough motors from various manufacturer's recently that I am beginning to wish designers would either use 12.9 steel screws or abandon the screw design for the old c-clip. The only way I am going to get this one out is to break out the dremel and then I've ruined the screw. My other complaint is that the internal portion of the shaft is 3mm instead of the usual 4mm on these hollow shaft designs. That saves weight, but I'm concerned about the long-term durability of that decision. It may prove to be fine with this design, but it is definitely something to watch. The motor is extremely smooth and the overall quality is still very solid.
Results
The results here showed some improvement over the previous design, though not quite as much as I had hoped. The KV tested a bit lower than I anticipated, coming in at 2250kv. The results here are decent, performing essentially on par with the first generation N52 motors such as the original RS2205. The lower KV means it does a bit better on the heavier props, making this a decent option for a light weight 6" build on something like a HQ 6x3.5 or KingKong 6x4. As always be sure to check out the full data sheet above and run some comparisons in the data explorer.
