Deal Extreme A2212S 2700 Kv motor bench test results

Hi everyone -

I'm a very happy park jet pilot to report that the DX 2700 Kv http://www.dx.com/p/a2212s-2700kv-outrunner-brushless-motor-45134#.VDk7nmddXkV is the same motor as the FP 2700 motor http://www.focalprice.com/YO090X/A2212_2200KV_Outrunner_Brushless_Motor_for_Airplane.html... :)

I only did one quick bench test with my ESC timing set to low and the numbers tell the story.  For the test, I used a Turnigy Plush 40A ESC http://hobbyking.com/hobbyking/store/__2165__TURNIGY_Plush_40amp_Speed_Controller.html, a balanced 6x3 EMP prop http://www.rctimer.com/product-218.html and this 2200 3S 40C discharge battery which I will be using about 90% of the time with this motor in my planes http://hobbyking.com/hobbyking/store/__9942__ZIPPY_Flightmax_2200mAh_3S1P_40C.html

So here are the results.

• At 50% throttle, the motor drew 12.5A and produced 148.8W and 515 gr/18.2 oz of thrust; and
• at 100% throttle, the motor drew 36.1A and produced 423.4W and 1047 gr/37 oz of thrust.

So other than a couple minor differences in numbers (remembering not all motors are created equal), the energy consumption and power and thrust production of the DX 2700 Kv motor is exactly the same as the FP 2700 motor which is very good news as it expands the availability of this amazing little motor... :)

I'm going to put it into my workhorse RCP F18 V3 for a quick field test as soon as the weather is nicer.

So "two thumbs up" for this DX 2700 motor.  I would probably not try it with anything other than the 6x3 EMP prop as from my experience testing the FP 2700 motor, it ran very, very warm with a 6x4 prop and didn't give noticeably better performance at the field.  You will need to purchase a 3.17 mm prop collet http://www.rctimer.com/product-580.html to attach the prop to the motor, I would definitely not use the prop saver and thin rubber band setup that comes with it, you would be asking for big trouble and it could be potentially very unsafe when a sharp prop spinning at close to 30,000 RPM comes flying off your plane... :/  Also, you will need to have male connectors to solder onto the motor leads as none come with the motor.

As mentioned in the last post, shipping was fairly quick, although I live on the west coast of Canada, so not as far for the package to get to me from China as it might be for where you live.  As with Focal Price, if you buy 3 or more motors, the price drops by $1.40 USD per motor and shipping is still free if you want to have a couple spare motors in case you go on a "building binge"  :).  

Cheers,

Scott
