The HK Mi Series servos represent the next break through in high precision servo technology. Using Magnetic Induction, rather than a potentiometer, for an unsurpassed level of accuracy and performance.
Speed: 0.08sec/60deg (4.8v)
Torque: 3kg.cm (4.8v)
Size: 35.6mm x 15mm x 31.5
Gear Train: Full Titanium Alloy
Spline Count: 25
Mi : Magnetic Induction, uses a Magnetic Rotary Encoder in place of a traditional potentiometer (invented in 1877). Magnetic Rotary encoders have a longer life and suffer less wear.

The servo performed good for four flights then just went dead. I feel ripped off. Should have just went with the Align or Futaba Rudder servo. What are you saving If the servo only works for four flights.Replaced the Futaba 9650 on my t-rex tail with one of these, HUGE upgrade for less than half the price. Works great with my gy401.Use this on a 500 and it performs smooth and steady. They only show this servo for 4.8V - Would be nice if they state if it can be used on 5.5 or 6V because the other HK28013DMG states upto 6V in the specs? I would think they have the same motors? I've been using it at 5.5V with no issues after a couple dozen flights.Using this as a tail servo for the Gartt GT500TT-FBL kit. should be fast enough and with adequate torque. Fits perfectly within the frame of an internal tail servo.These are very nice MG servos. The quality is very good, I have them on my 450 PROs , fits nicely. Crashed my heli many times but the servo is still solid. I have used it with HK401B , GA-250 and Tarot ZYX gyros and works great . I still do sports flying so no Comments on 3D . Been approx 1 year and performs the same . If you are looking for a Long life servo With Nice performance then you should go with this. Even The SPARES are available for this servoI bought three pieces. I wanted to use as a tail on the HK450-PRO, and HK500. All have failed. I think they do not run at 333kg. I do not recommend this product.Not as good as expected, but still niceReceived it today . Had a compatiblity doubt with HK401b , but it is working superb with the HK401B . No Heat issue or motor failure . Not installed on my HK450pro yet but i think it will work like a charm!good and powerful servo. i use for tricopter. to rotate the motor, . . 0.03. .
Servo is not bad, but to use as a tail can not drive. The claimed speed is not the case. At least in the 0.03s slower. Very good positioning accuracy.
