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.

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).

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 got the Miuzei servos. Tell me if this is normal with servos because I'm kind of new to RC. When I move the control stick and the servo arm moves, the servo arm stops very slowly even after the control stick on the Tx stops. It's like the servo has a built in exp to them. I'm not sure I explained this right but let me know if you understand the issue please. thanks

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!

It looks like you have a Tower Pro Counterfeit and a Tower Pro copy

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.

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.

I'm glad I could help.

It's a shame, real brand name Tower Pro servos are generally very good they unfortunately are subject to being ripped off and bad copies get out there. I've been burned before with the same issue. Emax has some decent budget servos and have a scratch off identification tag on the boxes to authenticate they are the real deal.

Thanks for that information!

yeah, I have a similar experience doing my senior project. I thought it was my code or design mess up, but really just the garbage servo :(

Sorry to hear that. Appreciate your comment.

This is amazon brother, even though, I don't understand this "Why do you buy from amazon?". We all know that Amazon is an American company that looks out for money more than the quality of their stuff. Still, I am sure that 90% of their products on amazon are from China. If you buy from china, it is much better and WAY cheaper, you bought this for 1.7$, eh that is goddamn a lot. I can buy it with 0.6$ per each from Aliexpress and if it was broken, I can open a dispute and make them pay me back with recording a video as a proof for the chineese company.

Thanks! I will look into Aliexpress.

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.

Good advice thanks!

buy MR995 (rotate) or MG996R (180 degree) for 3 USD and you have metal gear and 13 kgcm

' i use very good HiTec / Traxxas servos are good on my any R/C tamiyas / traxxases... few futabas servos

I was wondering what the hell is wrong with my servo, it just won’t center. Thanks

I bought the pack of 5 of that tower pro person and out of 5 none are working, I mean they literally now moving. Should have watched this video before buying it, sigh

I figured dont use blue plastic servos on anything great for small.light weight projects etc i tried them on my trex450 and wow they over correct too much and it shakes back and forth the helicopter and when I did a hard landing they all broke lol

The best way I know is to replace it with a good gear from a bad servo.

It's a hit and miss with all of these cheap servos in my experience.
