This is the hyper little brother of the Oomph 2206 2300kv, trading weight for KV.
Coming down from 2206 to 2205 on this motor definitely has an impact on performance. The reduced stator height trades torque for higher RPMs, but practically speaking that means this motor will be more focused on lighter loaded props like the 5x4x3 or Cyclone 5x4.5x3. While it is certainly capable of pushing heavier props thanks to the relatively conservative 2550kv, the lack of torque will impact the transition speeds, and you'll be more likely to get difficult to remove bounce-back on hard recoveries, and the characterstic "snap" of the high torque 2206s will be missing. The 2205 and higher KV also trades off some of the impressive efficiency of the 2206s. On the 5x4x3 it actually outperforms the 2206 variant, but at significantly higher current draw, just over 1300g at 33A for the 2205 and just over 1270g at 28A for the 2206. On the 5x4x4, a slightly heavier prop, the difference is even more pronounced, with almost identical thrust at just under 1400g, but 35A on the 2205 and 31A on the 2206. That current draw difference minimizes at lower throttle but never completely goes away. Still some very impressive performance from a 2205, matching the original RS2206 2600kv quite closely with a bit better efficiency, which given the significanly lower KV is an interesting analysis.
