Description

MG90S Metal Gear Digital Servo 450 Electric Straight Swashplate ServoProduct model: MG90SProduct size: 22.812.228.5mmProduct weight: 13.6gWorking voltage: DC4.8V-6.0VWorking temperature: 0℃-55℃Reaction speed: working speed: 0.11±0.01 second/60°(4.8V); 0.10±0.01 second/60°(6.0V)Stall torque: 1.6±0.01kg/cm (4.8V); 1.8±0.01kg/cm (6.0V)Working angle: 90±5°Angle deviation of left and right movement: ≤3°Response pulse width time: 5usecInterface type: JR, FUTABA generalThe package contains: MG90S servo motor × 8, multi-function swing arm × 24, fixed screw × 24Control principle: The control signal enters the signal modulation chip from the channel of the receiver to obtain the DC bias voltage. There is a reference circuit inside it, which produces a reference signal with a period of 20ms and a width of 1.5ms.The direct bias voltage is compared with the voltage of the potentiometer to obtain a voltage difference output. Finally, the positive and negative voltage difference is output to the motor drive chip to determine the positive and negative rotation of the motor. When the motor speed is constant, the potentiometer is driven to rotate through the cascade reduction gear, so that the voltage difference is 0 and the motor stops rotating. The control of the steering gear generally requires a time base pulse of about 20ms. The high-level part of the pulse is generally the angle control pulse part in the range of 0.5ms-2ms, with a total interval of 2ms. Taking the 180 degree angle servo as an example, the corresponding control relationship is as follows:0.5ms--------------0 degrees; 1.0ms------------45 degrees; 1.5ms------------90 degrees; 2.0ms-----------135 degrees; 2.5ms-----------180 degrees。

  • Basically old tower pro 9g metal gear knockoffs
Needed a bunch of 9g metal gear servos. These are not super fast and on occasion you get a bad one but for cost not a real concern. They come in reversed operation but fairly easy to open and swap wires around if need normal operation. Slightly bigger than say the stock 9g servos in many e-flite planes but work fine as replacements which is my normal use of these. ... show more

  • So far so good..
these work for many different applications whether it be an RC Heli, plane, boat ,car,etc,.. So far so good. They have been working flawlessly.. Good price as well. I actually these due to them costing less than other brands made of same materials..So as long as price stays low, I will keep buying them.. ... show more

  • We'll see...
I tested all 8 servos and had only one bad one. Hopefully the other 7 will hold up, and at about 3 bucks apiece for the $20 I paid for them it's still a good deal. We'll see...

  • meh.... 80% working
two of the 8 servos were dead upon arrival. one died after installation. sort of a bummer, but I guess you get what you pay for....

  • sloppy, but they do work
The output shaft is very sloppy and results in a lot of play in the servo arm. That play will likely be magnified on whatever you're controlling. I tried putting them in a plane, but it was way too sloppy for any control surface. I spent a few bucks more at HobbyKing and got something that was much better. I'll keep these servos for tinkering projects, but I won't be using them for any kind of RC vehicle control. ... show more

  • Some work ok and others not so much.
These are ok for things you aren't looking for smooth movement from. I am using them in a small robot project and they seem to have plenty of power to move weight...they are jittery in certain movements and I can not smooth them out. I noticed some of mine are sloppy in the gears and others are good. I did take one apart and it appears they are metal gears unlike some other people who have claimed these MG servos are not actually metal gears. ... show more

  • Very weak.
These are extremely weak. Definitely not up to par compared to other 9g servos.
