Recently I picked up a couple of Gear Best A2212/6T 2200 Kv motors to try out as a "mild" alternative for our NAMC parts list. I happened upon it when I was buying the A2212/5T 2700 Kv motor from Gear Best (GB) that you can read about in this thread. At that time, the price for the 2200 Kv motor was $5.83 USD, a tough deal to beat :) However, since my motors arrived in the mail, GB is currently out of stock and the price has jumped to $9.22 at the time of writing this post. However, GB seems to run specials on these goodies quite often, so perhaps the price will come down again.
Here is a picture of it in one of my Mig-35Bs
Before putting this motor in the plane, I did a quick bench test. I'm using a Turnigy Plush 40A ESC, timing set to low, Zippy Flightmax 2200 3S 40C battery and 6x4 APC prop
50% throttle - 10.9A/132.8W/400 gr/14.1 oz of thrust
100% throttle - 29.2A/347.3A/786 gr/27.7 oz of thrust
When I first saw these numbers, I was wondering if I had a 2700 Kv motor instead that had been labelled incorrectly as the numbers are almost identical to the bench test numbers I saw with the GB 2700 Kv motor. Perhaps the 2700 Kv motor I tested was incorrectly labelled as I think I bench tested a different one than is in the plane I used at the field. More work to do there.
Yesterday while testing this motor at the field, I also flew my Mig-35B with the GB 2700 Kv motor and there is definitely a difference. Both these planes weigh the same, but top end speed is better with the GB 2700 motor and I can tell by the sound it is spinning higher RPM.
The numbers above are pretty good for a 2212/6 2200 Kv motor in my experience, this GB 2200 definitely ran stronger than the Turnigy D2826/6 2200 Kv motor I had been running in this plane previously.
I'm not going to jump to the conclusion that it is stronger than many other 2212/6 2200 Kv motors I have ever used just yet, I have had Turnigy D2826/6 2200 Kv motors that ran stronger than this and also weaker than this, you get what you pay for sometimes with these inexpensive motors, so I feel fortunate this one performs as advertised and maybe even a little bit better.
I have run 15 batteries through it thus far, lots of full throttle and vertical climb outs to start putting some work into the motor. The temperature while I was flying was 18C/64 F. The motor was warm after landing, but not warm to the point I couldn't comfortably put my finger on it for at least 10 seconds after landing.
I am very pleased with how it continues to provide power over the whole throttle spectrum. Meaning from 50 to 100% throttle it continued to provide more RPM, power and speed until at full throttle. Sometimes with other 2200 Kv motors I have tested, even with the throttle points being set several times, it seemed that the motor maxed out at about 80% throttle, so it is nice to get power over the whole spectrum.
I purchased a second GB 2200 motor as well which I will test to see if there is any difference in the performance.
More to follow in the coming weeks as I test this motor for it's durability and performance over time, fingers crossed GB drops the price again, tough to beat $5.83 USD for this little motor :)
