De HK Mi-serie servo's vertegenwoordigen de volgende doorbraak in hoge precisie servo-technologie. Met behulp van magnetische inductie in plaats van een potentiometer, ze bieden een onovertroffen niveau van nauwkeurigheid en prestaties, tenslotte HV bedrijfsspanningen betekent dit servo kan direct opereren vanuit een 2s LiPoly batterij, waardoor de noodzaak voor spanning vermindering apparaten zoals UBECs en regelgevende instanties voor extra gemoedsrust .

Tested, disassembled and inspected these. Great servo, but are more than powerful enough to destroy themselves if ran hard past the stops. I did inadvertantly it. It was over in a fraction of a second. Incredibly the servo continues to work but runs continously. The final titianum gear teeth stripped and it deflected intermediate shaft bushing in the housing - A metal housing would withstand more abuse but at a substantial weight penalty. At this torque level something's gonna break somewhere if you screw up.
That being said, these are absolutely brutal. They will destroy almost anything you can hook to them (In a giant scale aircraft anyways). I am using 3mm steel rod ends and titianum pushrods and it will probably fail that but I'm sure it would simply rip the aileron off the wing 1st. These are fast, precise, center perfectly are and easily the equal of any $200 name brand servo. If you want a great servo and aren't hung up on names, you'll love this servo.bought this , bench tested in car, great turn and speed however stripped out with minutes of first run , complete waste of money and timeOk, I have it. Wowe what a Power, no Chance to stop it with my Hands. And a realy high precition servo with very lowe noise. I also have the smaler one's with 7kg and 11kg torque and hope HK will bring them in the EU-shop. Don't try to test it with a normal analog Servo-Tester. It will only work with a digital Tester ore your digital receiver.Bought one for steering in Axial Wraith, and ran it with 6,2 volts since my rear steering servo cant take more. On the table and indoor testing it seemed fine, little noisy, and centering wasn`t 10/10. But when went driving offroad, it took whole 10-15 minutes before first squeek from it. I drove the rest of my comp with it, squeekin got a little worse. Funny thing was you could drive normally with it but when more torque were needed it started to yell.. Didn`t sound like output gear at all.. When opened it was second gear what had jumped teeth. Yup, gear are like butter and engagement is poor, also notised that as too much slop. And that 47XX gear set doesnt solve this problem so now I have a servo in which I cant get replacement parts..
For rc-cars, be warned if you buy this.
For rc-planes, do yourself a favor and dont buy this one.
I've been using a few of these in different scale trucks and crawlers, and they are crazy strong. I have them all wired directly to the 2s battery. TONs of power, and work very well. Not very loud, center perfectly. I have actually burned out one of the circuit boards by flicking the steering back and forth so fast it Overloaded and fried. My fault, I turned down the steering TX speed, and now they last forever. I also have the 23kg ones, just as good! Great servos!!Purchased one for my crawler. Looks nice, is strong, not too much slop pn the gears.
Unfortunately during the 4th 850mAh battery pack (30 min run all together) the gear stripped. It seems the gear material isn't that good.Not the cheapest product, but one of the best servos that I have ever tested. No gearplay, excellent centering, and no shaking on all the flapps, it is an excelent choice for big 3D machines. You can change it with the Hitec premium products without compromise. My endurance test with around 100`000 Cycles under load (50Ncm) attested that the characteristics of this Servo are the same as before.
The price of the incredible Power is the high energy consumption. It can pull up to 4.5 amps at 6 volts! If you use a lot of this servos-types you have the look for a rock solid power supply.
Started out AWESOME, ended not so much. I bought 3 of these, all for rock crawler/trail rigs. All 3 of them ended with a stripped main output gear. Apparently all of the other gears are Titanium and the main output gear is Aluminum (butter). There seems to be a little too much backlash between the output gear and the previous one. These servos are plenty strong, ran one @ 7.0v for a bit, the others were ran @ 6.0v. Honestly, the last gear should've been something other than Aluminum, steel sould've been a much better option in my opinion. Really can't recommend these, sorry.Review.
Bought one for testing,
Speed .16 to 60 degrees
Very noisy, MIE always working and buzzing.
MIE very slow around center
Poor centering due to loose gear train, too much backlash.
Good , strong servo, but not for precision aircraft.
the Hobbyking BL-84601 Digital Brushless MG HV Servo 16.10kg non MI , kicks its butt for accuracy but not speed or power.I put this servo in my Traxxas Summit 1/10 instead of the double traxxas stock ones, it's as fast as the stock traxxas servos but waay much stronger and that is at the power from the ESC, probably going to get even stronger and faster if used with 7.4 volt.
