This is a new motor from a new manufacturer, iFlymodel, who sent it over for testing.
This has been my first introduction to iFlymodel, as I had never actually heard of them before they contacted me about testing their motor. Given the unkowns, I was very curious about this motor. The build quality is quite good, tolernaces are quite tight there is no play in the bearings either before or after the test sequence. The design is a bit of an older design, with integrated prop shaft, 3mm internal shaft, square magnets and multistrand windings. That being said, the airgap is quite tight, the magnets are quite thick though a bit narrow, and physical design of the motor is quite well thought out. The base leaves plenty of clearance for the windings over teh screw holes, and the top of the bell is designed in a way that allows a good grip when changing props. All this was managed at a relatively reasonable 28g. Overall, the motor is solid quality, though nothing in particular stands out.
Now on to the bench results!
Again, as a newcomer to the motor scene, this motor was a bit of a mystery to me and I was interested to see how it would do on the bench. Performance was solid middle of the road. Nothing amazing, but very solid results. The results across the board were almost identical to the original Emax RS2205 2300kv, which by modern standards has fallen behind a bit, but is still very respectable. The one caveat to this motor is that it seems to need higher timing, especially on the heavier props. The 5x4.5BN prop in particular gave this motor trouble, and I could never get it to hold sync on the idle to full throttle transition, even on med-high timing. Possibly high timing and high demag may solve the issue, but for now I would recommend sticking to other props, such as the 5x4x3, or even the KingKong 6x4 if you happen to be flying this motor and making sure you run medium-high timing. Aside from that one hiccup, the results were fairly solid with no sync problems on med-high.
