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.
Voltage: 4.8v / 6v
Speed: 0.05sec / 60deg (4.8v) - 0.04 /60deg (6v)

I got this thinking "awesome speed for the money" yes it was quick.. but not for long..
After 3 laps och drifting it started acting odd. The center position changed after every turn. I decided I will open the servo and see what the issue is.
The problem was that it had small plastic parts to prevent the servo from spinning to much. These broke. I guess that the speed and tourqe of the servo broke them of. I then checked anoter servo that is both slower and weaker from another company and they had these small parts in metal.
Not worth it and poor design.
Should be used as tailservo on helis only with the analo setup of the gyro. Works great, touh, but with higher frequencies it get hot nearly imediately. Runs smooth and is very fast. Holds tail rock solid. Will come back with further update after a number of flights to report, how it lasts.Fitted to my drifter. Great servo, very fast. Only slightly larger than the BMS-661DMGplusHS it replaced. Fitted futaba servo horn fine.Aufnahmeritzel hat radiales Spiel! Hat aber trotzdem 3 Std. am Heck bei einem 550 Heli gut funktioniert, dann schmorte der Motor duch....Si, questo servo veloce, l'ho montato sul mio hk600gt come servo di coda, devo ancora provarlo in volo, per come prima impressione sembra ok............for 600 heli tail only work on 1520/71hz :( if you force it with 250 or 333 hz the servo will be cook itself :p-btw i must pay about 16 usd for MI (Magnetic Induction technology)Moderno servo de cola a muy buen precio.don't used this one for engine heli 50-90 this not engine vibration resistance....that will make err servo which will make the move and can not be stopped :(std. size servo
digital high speedMuy buen producto,
suave, digital, y muy, muy rpido
ideal para cualquier heli a partir de 500 o 50.
Va de fabula con los clones del 401 de hobbyking, pero hay que quitarle mucha ganancia en el end-point de ch.5..
