[8-Pack] MG90S 9g Servo Motor Micro Metal Gear for Robot Car Plane RC Helicopter Arduino

Good morning. I was having problems with these motors. But the problem was my fault. I had stopped paying attention to the voltage these are rated for. They say 4.5 volts. I was using a 12V power supply at 2 amps. The motor would work fine for a few seconds, then it would lag. My guess is that it was overloading or overheating. When I switched to a lower voltage (I have 7.5v 2amp) I noticed that this now works perfectly. So, use the right voltage on your power supply, and you should be good to go.

I like to build and fly hard. These are perfect. They are fairly accurate and you don't have to worry if you crash or just can't pull it from an old model, cheap enough to toss.They do work well, I have 2 in boats and 5 in planes, all have worked without fail until the craft was destroyed.Nice, cheap and work well!

Plastic Rudder servo on an Arrows Bigfoot didn't last too long with all the vibration. Replaced elevator & Rudder servos with these & they are smooth as butter. Never fly with plastic geared elevator servos! 3$ insurance!

I bought a 12 pack. 11 worked and one was dead (locked up gear). The servo’s are not at the same level of quality control. Some are made better. Overall decent for the money. No idea how one returns one servo..

Servos often fail and cause disappointment. These were good to go out of the box. Happy I chose these for my RC plane project.

These are just junk, not much else to say about them, so far 3 out of 4 have issues, instead of working continuously they hesitate. Haven't tried the 4th one but I think I can expect the same results from it.

My first time working with servos I tried those similar to these with plastic gears costing a little less but found they didn't hold up and soon they gave up and died and were noisy. These on the other hand are very quiet and are consistent in positioning, whereas the cheaper ones would sometimes twitch back and forth. I have bought these before and have just ordered a dozen more feeling confident they will hold up. I recommend these motors.

When tested on my servo tester three of the four operated properly, the third exhibited significant twitching/dithering. These were purchased to replace one with a similar issue in an airplane. A replacement would be appreciated.
