Mi Digital High Torque Metal Gear Servo JR/Hitec 11.8kg / 0.07 / 58g
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.
A great servo for 550~600 Class helicopters such as the T-Rex 550 and HK600
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.
Hello Frank,
I'm curious to know if you tried to fit this servo in your Team Associated cars. I'm a bit worried because the size seems bigger than my EXI 227F, which is already a tight fit for me in my SC10 and T4.1. Still, it seems a bit smaller than the Solar Servo D771, which I'm told can be made to fit with some grinding.
Thanks!
If you put these servos on your HK600GT, you will experience problem fitting both aeileron servos. They are to high for the HK600GT frame I had to put 3mm distance plate between servo and heliopter frame on each side. now it is OK.
Anyone know if this works with the GA-250 (Assan) gyro? The specs do not mention the timing settings and I don't want to fry this fine servo. TIA!http://www.hobbyking.com/hobbyking/store/images/ em_nerd.gif
Is there a way to switch between 4,8V / 6V operating mode? Need to check if there is some BEC issues with me esc, i am getting brownouts a couple of minutes into racing (1:10 short course)
JR and Futaba have a different number of splines. you may be able to force plastic servo horns on either, however if you use metal servo horns then they are not interchangable. So therefore my question still stands, Are they Futaba splines?
That's the same question I have. For a few dollars difference in price, there should be something different. They look identical and even use the same picture in the exploded view. The 47111 is 3g heavier than the 47011. My guess is thicker/heavier gears for RC cars steering use on the 47111.
Yeah mine makes the jittering noise but works fast and strong good central return. Not sure why it jitters I use CC 10AMP BEC set to 6v and 2.4GHz Rx/Tx but it works thus far.
It's normal for them to growl while at rest, I have three of the mini sized one and a high speed standard sized one on my 500 size helicopter and it sounds like a Geiger counter with all 4 servos buzzing. It's because they have a very small deadband (the amount it can move before it tries to correct it's position) and as a result it's *always* making little corrections which is where the buzzing sound comes from.
Yes it will...that is what I am using them on. They are surprisingly fast...their claim of .07 is pretty spot on. I believe they are the best bang for the buck.
Yes it's true. It's a very fast servo. I HAD one. Stripped the gears on it after a very BIG hit landing a jump. But don't get me wrong. It's a very good servo. I would buy another anytime.
From a Blue Arrow product list I found online..
Red one is the DMS47011MG which has a nylon center section.
Black one is the DMS47111MG which has an aluminum center section.
Both are 1520us.
Both are intended for planes, helis, cars, trucks, boats.
I hope HC gets some 760us ones in stock.
Whats the dif. between this one and the black case one other than how tall it it. Dont make sense why this one would be that short. If the hight is a misprint then why a dif. price. Red dye is cheaper maybe? :-)
Don't run these at over 280hz, the digital amplifier can handle the frequency (as per the specs on blue Arrow's website) but the servo's heat dissipation isn't enough to get rid of the excess heat and it will cook itself to death, especially if used on a gyro. Stay at 250hz and it's a good servo.
Actually I take that back, they seem to run fine at 333hz with no overheating. It may depend on your gyro. I would try running it at 333hz and if it starts getting too hot drop down to 250hz YMMV
I use 3 on my HK600GT FBL on cyclic, had to use spacers for ailerons but no big deal, they are fast and center well. Using at 6 Volts on a CC BEC Pro, have about 10 or so flights now and still working great.

This is the servo that I have been waiting from hobbyking. Fast and with huge torque. The servo is being used on a bugy and a monster truck on its own and wow this thing is stroooong and sooo fast. Hobbyking please stob bringing these awful servos that you claim as fast with 0.16 speed and high torque with 5 kg. This is a real servo In a real price!!1

I mounted it in my Tamiya TT01D-typeE chassis. Fits perfectly. This servo is very good. After 15 hours of use I am very pleased with it (fast, strong and accurate).

I'm using this servo for past two months on my 1/8 buggy and it works like a charm. I had some problems on the first run, since than it works perfect. I noticed that this servo has big power consumption so I installed UBEC.
