  Comments: Be careful, the chinese clones I got (3 different ones) are all only capable of 170 degree rotational angle. They are faster and unexpectedly draw less current than the analog SG90 ones!

  Comments: There are fakes being sold at some of the usual online sellers, if all yours are bad they might be fake . Great servo, but dont expect $50 quality for $8.

  Application(s): 39" EPP SU-29 (400g)

  Comments: Bought 4 of the MG90s servos, 1 was DOA. Bought one MG90 to replace and found that one locks up easily if any force is put on the shaft, and the MG90s also has a lot of gear slop. So I had to purchase 5 servos for a 4-servo airplane. They are now working. Centering seems decent, resolution seems VERY low.

  You get what you pay for. Period. I like nice stuff so I will not be buying these again. They came in a "power pack" with an airplane which was highly regarded so I gave them a shot. I have regretted it since.

  Application(s): Swashplates servos for Trex450 clone

  Comments: Well, I really like them. I've used two groups of three for my Trex 450 clone swashplate, and they worked really nice to me. I crashed with the first batch several times, since I was learning, and they resisted it very well. Finally I replaced them all, since they finally developed some jittering and sloppyness. I can't blame them, too many hits. They are not very fast, but they do the job for a novice pilot, since thieir metal gears are very forgiving. BTW, if you use a Corona MG919 as tail servo, add a ferrite coil to that other servos, in order to avoid some jittering with these ones.

  Application(s): Used 12 of the MG90S on a 16 channel PWM controller.

  Comments: I bought these two different times and received different products... Both were labeled MG90S. The first came in a solid black plastic case with a smaller spline. The second came in a charcoal translucent case with a slightly larger spline. The first seems to work somewhat reliably under load. I burnt out a few because I was using 7v power supply to maximize torque. They would work fun until getting bound up on something... So you probably want to stay with the rated 5v or 6v at most. I also had several tabs break off as someone else mentioned. Otherwise with the right care these seem like decent little value servos. The second batch (translucent case) I ordered from AliExpress and I think I received fakes. In the same board, they are twitchy and not smooth and don't seem to have the same torque. I bought 16 of them so I'm not happy. Did anyone else have this problem? Is there something different I should do with these?

  Application(s): Cyclics on Trex 450 Pro

  Comments: I must say that these servos are best buy. They are precise, they centering very well, they don't buzz and main advantage that they are very powerful. Now I'm sure that these are not going to die in middle of flight.
  But be aware where you buy these servos. Some of them are clones that come with smaller motor. These are very weak, torque is lower than cheap HXT900 servos.

  If you are sure that you can buy original MG90 servos and not clones than I highly recommend them.

  Application(s): Cyclics on T Rex 450's.

  Comments: Good servos with weak mounting tabs. Must be VERY gentle on install and service because they DO break very easily. Use rubber padding between tab and mounting surface and you'll have a reliable setup.

  Application(s): ailerons

  Comments: Haven't used them very much yet:I wonder if the user who had lugs break tried to fit screws through the indents on the lugs instead of the screw hole in the centre? Just a thought?

  Application(s): Trex 450 Pro

  Comments: Tabs broke off on all three servos during install and or reinstall setup. The case tabs are very very weak. Poor quality! Only tried to snug them up so they would hold and let the thread lock hold the screw.

  Application(s): 450 heli swashplate

  Comments: Maybe a bit too large for a "dressed" DS450 V2 but really strong and precise! I use them as swash servos driven by a 3X1000 3 axis in an Ecureuil semiscale, rigid triblade head...well: fantastic! No drifts, no shakes, the machine stands in the air like a rock in the ground! Much better then Align DS510 on my CX500 FBL where the 3X1000 was previously mounted.

  Application(s): DO NOT follow #2 reviewer's advice on manually rotating the servo arm, it is not recommended (fact), period. used as aileron servo('s), rudder and elevator on small to medium 3d-foamies.

  Comments: out of 30 or so bought, maybe 3 bad. (out of the box) some were noisier than others. at $7.00 or less online they're a good deal. (opinion)
  my experience: stayed at a holiday inn one time

  Comments: 4 Helis and 2 planes were built using these servos and they all still work very well after many flights. I use the MG90S
  version. All center well and no slop...will continue to use them.

  Application(s): 450 electric T-rex clone.

  Comments: I don't want to use these for anything that flies. All four in my copter lock up, if occurs some twisting that pushes axle inwards the servo. I might have "monday individuals", as usually I have read good reviews about these, but if you already have one of these, do a following test: manually rotate servo arm. It should rotate gently. Then apply very tiny pressure like pushing the axle into the servo and then try to twist. Those of mine are completely locked in place, until I pull the axle. I don't want my servos lock in place in the air!

  Application(s): Any use. suits all uses.

  Comments: Good centering. Very strong and lightweight for a metal gear servo. This servo is an ultra low cost servo and can be sued in many situations :

  - As a gear servo on mini car 1/18, 1/16GP etc..
  - Rudder, Yaw, ailerons servos as it is enough fast to perform such abilities.
  - Mecanical for mini retracts on less than 500 grams planes.
  - Mini robots.

  It's a very cheap servo, and for the price, there will be no deception for low cost project.
