These Are the Servos That Worked for Me - Miuzei SG90 9G Micro Servo: amzn.to/2KyvPg4
As an Amazon Associate I earn from qualifying purchases. This helps support my channel without any additional cost to you. Thank You!
I recently bought 10 small Tower Pro sg90 nano servo motors from Amazon for my Flite Test style Dollar tree foam board RC airplanes. What I found out was surprising.
Just because the servo is cheap, doesn't mean it's junk. Likewise, an expensive servo isn't necessarily a good quality servo.
You may be looking for servos to use in radio control Airplanes, cars & trucks or are wanting to purchase pico or sub micro servos for a robot or Arduino project. If so, you should seriously consider heeding the warnings of this video.
You can always buy the Higher-quality servos such as hitec at Tower hobbies, Hobby town and hobby express. The name brand servos will most likely cost more money but will hopefully have a better quality and longer life.
But if you're wanting to save some money, you can buy less expensive servos at Amazon and hobby King. However, quality could be an issue.

I'm just getting started programming hardware and I wouldn't have thought of the importance of "return to zero" until you pointed it out and related it to flying. Huge aero fan and yeah I could see how this would just be rotten to the core. Funny thing is I bought a cheap adeept electronics kit to start this venture and while watching this video pulled out the servo, same one but? It has the green potentiometer. It is the Tower Pro brand model everything else the same. Going to connect it up and run my own return to zero tests. THANKS ROBERT!

A simple case of a batch of servos that failed a QC check b4 the label was put on it. Then the whole batch was sold cheap to a seller that was willing to deal with dissatisfied customers. You can declare a loss selling the bad batch, but you can't declare a loss just throwing them away. Thanks for the heads up and as always...buyer beware.

Interesting video. Never experienced this and have a lot of those tower pro servo's in little home made depron planes and converted toy rc cars. Maybe they are all doing this since none of those planes fly straight ever. but I had the idea this had to do with every time different batteries and mini camera on or off the plane, wings not perfect in the same place because elastic band mounting etc. Not a nice way to fly but will make you a better pilot in the end because you learn to fly with airplanes that never fly consistent. Have to do a check like you did. Thanks!

I have 2 robot arms from Adeept and having the same problem with their brand of servos AD002's. After only 1 week of operation 1 servo stopped working, and 3 slip like crazy. These servos jerk out of alignment so fast, so much, and so bad that the robots will NOT repeat the same action that I record, they go off that bad. I ordered some Tower Pro's before seeing this video. I find the evidence inconclusive on ALL servos! Its most likely that ALL servos are made by the same company that just puts different stickers on them for the seller of their products. This is done for many products, such as batteries! All batteries come from the same manufacturer, all of them are made the same, the only difference is the brand name put on them! Same thing is going on with these cheap POS from China! All garbage, cheap crap, and hit and miss on a servo to servo basis!!!

I just looked at the one that came with a Arduino kit that I bought last year. Mine is the Tower Pro with the "TP" on the plastic case, EXCEPT it has the green band on the edge like your Miuzei does. I have no way of testing them because I haven't built a plane and don't know how to test otherwise. You might find a use for a simple switched back and forth servo. Something where you have a detector that has it run till it hits a switch, or a sensor that makes it self correcting (meaning it keeps moving until a sensor says to stop).

Some work great and don't shift... and others will do exactly what you are showing. I found that I have to hold onto servo arm and move it. If they hold strong or return home by themselves when you let go, they are fine. I have around 50% failure rate.

I had a pack of these servos in my Amazon shopping basket and was wondering about them, well after viewing this video I went ahead and purchased a pack of 10 Muizei 9g servos to control points on my model railway layout. I'm sorry to say that my experience of these servos is not as good as yours and I have returned them to Amazon as not good enough quality. Why - instead of moving from one position to another at the throw of a switch they would move then jitter and when the switch was thrown in the opposite direction they would move but then jitter continually. I will be ordering some more of the original servos I ordered from Wize productions as they do not jitter on my current setup.

Confusingly, I have five miuzei MS18 9g servos with "TP" printed on the bottom and black potentiometers inside and a Tower Pro sg90 servo with a green potentiometer. The Miuzeis are from amazon prime and the tower pro comes from an arduino kit. From my experience, the tower pro works far better than the Miuzeis, which are less accurate and horribly unreliable. I guess those online sellers just put whatever brand stickers onto whatever servos.

I guess they might be alright for continuous rotation (since the potentiometer gets bypassed). But I must say that I wouldn't want to put the cheapest possible servos into airplanes anyway. And of course I've bought 10 servos for 17 bucks before watching this and now they're at home and I'm in the library and I can neither confirm nor deny the presence of crappy servos in my apartment until much later...

The "TP" may also refer to it being an unlabeled type of "Thermoplastic", as I have one with a "Miuzei" sticker and it says "TP". However, it has the black potentiometer inside so I took it apart and tested the POT in mine and found that it has a LOT of play in it before it changes the signal enough to move the motor. it also seems that the circuit on this servo outputs current to the motor proportional to the signal change from the POT, so at very small changes in angle, it doesn't output much current for the motor to use, so the torque is really low. Circuits in other Servos I have from "Miuzei" (with the yellow POT) always output consistent current regardless of the POT rate of change. Seems like a cheap workaround for counteracting something like the servo overshooting the target angle or something due to poor accuracy in the POT.

@@roberta.edinger9405 Thank YOU for the video! I didn't even notice that some of my servo's were bad until I saw it. Unfortunately, i can't think of a good solution. I'm not a certified electrical engineer so take my words with a grain of salt. They seem to use a slightly different microchip (I've found some with KC8801 and some with KC9806 and some that are unlabeled) so changing out the POT would probably just cause problems. You would need the datasheet for the specific chip, and then some kind of transistor switch that's controlled by the low output change from the POT spliced in between the POT and the microchip to rectify the low current. The best option is probably just finding a reliable supplier for the good batches of servos, if one exists.

How do they work at all without a potentiometer to tell the current output position? Or are they just pulsing the motor on for say 0.1 second one way and then 0.1 sec in reverse, which would explain the lack of accurate centering?

My advice is to always run your servos on a proper tester for a good few minutes each one before committing to the air. (but no offence to you at all but you know this now) We are all getting to know that Chinese stuff is totally hit and miss, its pretty good when it is good but mostly miss and the Chinese dont care too much about consistency in quality or longevity for that matter ( they are happy to change stuff thats crap but its the hassle) so if you get a good item or set - its just pure chance so at $17 for 10 of these suckers - you kinda get what you pay for. I do feel your frustration as you are the innocent party here, as the stuff should be fit for its purpose and work as intended. So I would pack it all up and send this junk back to Amazon for full refund, despite when they were bought. I feel Amazon are very much at blame for perpetuating poor quality products coming in from China by continuing to import without properly policing / checking this sub standard useless crap.
