MG90S 9g Servo Motor Micro Metal Gear for Robot Car Plane RC Helicopter Arduino

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!

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 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..

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!

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.

I would not recommend these to anyone,, I have 2 the got hot and 4 or 5 stopped workingI have had others that chatter, Soon as I put fms plastic servo in all problems stoppedSo much for metal gear servosGood price if quality is good but I will never buy these again or put in my airplanes.Very disappointedAmazon should post a warning to anyone buying this servos to be ware

All 4 servos tested good. They're reasonably quiet. Full metal gears: even the first 2 gears. Bronze bushing on the output, not a ball bearing, but that's ok. 90 degree range, not 180, but that's also ok. These are not waterproof, but I don't think it says they are in the description. (Water resistance is one of the features Amazon asks for a rating on.) We'll see how long they'll last in my 1/18 buggy. So far so good though. Thumbs up.

I didn't expect too much when I saw the price, but I was wrong! I use them on all of my small foamies and they seldom fail. I have only had failures caused by damage from hard crashes. They also arrived much earlier than promised.

I like these servos because they are light and strong enough for foam aircraft.

Used on a small drawing machine it works just like the original servos.

I bought 4, and one is so jittery it is unusable. Cheap price, cheap performance I guess.

2 failures out of 8 , the good ones are good though, they fail pretty fast when you stall them.
