This servo is quite highly regarded in the US, so I thought I'd try it. Here's the blurb:
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.
Specs:
Voltage: 4.8v / 6v
Speed: 0.08sec / 60deg (4.8v) - 0.07sec / 60deg (6v)
Torque: 9.70kg.cm (4.8v) - 11.8kg.com (6v)
Size: 40.2mm x 20.1mm x 39.2mm
Weight: 61g
Gear Train: Full Titanium Alloy
Motor: Coreless
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.
Super fast, torquey, quiet and smooth. Well, I say 'quiet' it actually runs quietly, but when at rest it chitters away like a chipmunk!
Anyway, it's light years better than the Alturn.
Doing a bit of diff oil experimenting. I'm changing the rear 3K oil for 7K oil. I think that may make it better under full power.

Jimmy, stop buying Chinese crap and just buy a Savox 1251 or 1258. You could have had one for the money you wasted on two cheap efforts. Everyone uses them because they are good and they work!
