- DYS MR2205 2300kv
This motor is one of the new batch of 2205 motors hitting the market right now, the DYS MR2205 2300kv. DYS sent this one over for testing, and here are the results. Once I've done the full bank of motors, I'll do a document sumarizing the direct comparisons.

Now on to the testing!
The new DYS MR series motors represent a significant change from the traditional DYS motor. The T-style mounts with prop adapters from the original 2204/1806 motors from DYS are gone, replaced with a sleek black matte finish and an integrated prop adapter. The motors are quite light and the windings look fantastic. They're the largest guage wire that can be successfully wound by machine. The windings are neat and tight. The bearings seem to be also a significant upgrade from the old DYS motors. Very smooth running and no notches or rough spots on the 8 motors I received in the MR series. There was also no vertical play on any of the motors I received for testing. Overall I was very impressed with this offering from DYS. I can see these becoming an economy standard in along the same lines as the BE1806 has been for years.
Now on to the bench results!
In terms of performance, these motors did very well. They basically stayed very close to the Cobra 2300kv through the entire run. On the 4" props and light weight 5" props the DYS MR outperformed or broke even with the Cobra. As it moved into the heavier props with higher load it lost a bit of ground, with the largest variance being the Gemfan 5x4.5 prop at a loss of about 30g and 300 RPMs to the Cobra. Most of the other probs varied by only about 10g. It's also worth noting the KV testing on this motor put it a bit over 2300kv at 2370kv. Most of the other motors (including the Cobra) have tested at closer to 2250-2290kv, which explaines the loss of RPM on some of the larger props on this motor. Overall for the price point this performance is extremely respectable. It's good to see a companies responding to market demand, and making products that satisfy the need.
