I recently received a new motor in the mail from Banggood, the DYS BE2208/7 2600 Kv. Here is a picture of it with a Master Airscrew (MA) 6x4x3 prop mounted on it.
The shipping from Banggood was free, it took about 4 weeks to get to me on the west coast of Canada from China. The motor is about 10 gr/.35 oz lighter than your typical 2212/6 2200 or 2700 Kv motor, the "can" is about 4 mm shorter, diameter is the same.
The quality of the finish and bearings seems excellent, the bearings are apparently made in Japan, not sure why that makes them better, but the motor spins very smoothly by hand.
Thus far, I have done bench testing with the 6x4 APC prop and the MA 6x4x3 prop, both tests conducted with a Turnigy Plush 60A ESC with timing set to low and a 2200 3S 40C battery.
Test results for the 6x4 APC
50% throttle - 11.8A/140.8W producing 405 gr/14.3 oz of thrust
100% throttle - 30.2A/364.8 W producing 710 gr/25 oz of thrust.
The thrust results are at the low end of what I have seen with the Turnigy D2826/6 2200 Kv motor. What I mean by low end is that I have seen this motor produce as high as 28-30 oz of thrust with this prop without problem, all depending on the batch it came from and quality control.
However, it is pulling about 20% more amps to get this thrust, so not a very efficient setup compared to other motors, the Turnigy D2826/6 2200 motor for example pulls only about 25A to get the same amount of thrust.

I chose this prop as this is the one that folks are raving about on the RC Powers forum to use with this motor. These props aren't cheap, I paid $6.99 Cdn (about $5.29 USD at time of this post) from Great Hobbies in Canada. They are very high quality props, made in California and came out of the package perfectly balanced (I bought two).
50% throttle - 12.1A/145.2W producing 425 gr/15 oz of thrust
100% throttle - 29.9A/338.0W producing 922 gr/32.5 oz of thrust.
So pretty decent numbers, about the same as what I have seen with the Gear Best 2212/5T 2700 Kv motor with 6x4 APC prop. I'm hoping performance at the field translates from the bench well. I have put this motor into one of my Mig-35Bs and will be testing it alongside my second Mig-35B with the GB 2700/6x4 APC setup to see how things go.
I'm also hoping it lasts me more than two dozen flights as my last DYS 2200 Kv motor turned out to be a bit of a dud :(. More to follow soon.
