In my continued testing of the Gear Best (GB) A2212/6T 2200 Kv motor, I really pushed this motor hard yesterday to see what sort of punishment it could withstand in rather extreme flying. I now have 35 flights on this motor in the white/blue/red Mig-35B shown below, all using a 6x4 APC prop, Turnigy Plush 40A ESC and Zippy Flightmax 2200 3S 40C battery.
This testing consists of at least 6 flights in rapid succession, no more than 60 seconds between landing and launch. During each flight, I do multiple aggressive accelerations where I take the throttle down to about 40%, let the plane slow down and then hammer the throttle to 100% followed by either a high speed run or a vertical climb out. During the vertical climb outs, I let them last at least 5 seconds to really put strain on the motor as it pushes the plane's weight against gravity.
Temperature conditions during this testing were 18C/64 F, at the end of the sixth flight, I checked the motor for heat, it was warmer than it would be after just one flight, but not to the point I couldn't comfortably keep my finger on it for at least 10 seconds. I was quite impressed as I had pushed the motor hard for almost 30 minutes non stop with the back to back flights.
So it is a pass for this GB 2200 Kv motor on the "torture test", in fact, the more I fly with this motor, the stronger it seems to get, I will remember to do another test on the wattmeter after 50 flights to see if there is any change from when I bench tested it right out of the package.
Now on to more and more flights testing it's durability and performance over time, thus far all test results have been excellent.
