10 Pcs SG90 9G Micro Servo Motor Kit for RC Robot Arm/Hand/Walking Helicopter Airplane Car Boat Control with Cable, Mini Servos for Arduino Project

These have held up well. Only used indoors but no issues with functionality. Currently use them for model armatures with a remote. Would be good for all kinds of modeling.

This is a nice set of these small servos that work well for my proof of concept project. They aren't super powerful, but not advertised as such, but they'll do the job for a project you might be planning that needs many multiple servos to work. I hooked one up to a servo controller and it worked well and was very quiet. 180 degrees of movement which will work fine for my project ahead. If you need a bunch of little plastic geared servos, this is a great assortment that will give you 10 of them. I'm very satisfied with the purchase. Just as advertised.

Great Part

The media could not be loaded. This little guy works just fine with Arduino Uno experimentation. One thing to be aware of is that the small little screw for attaching the horn to is a self tapping screw so, it is important that you align it very well when you’re screwing it in. This is difficult to do with fingers as big as mine as you can see in the video my screw is a little bit cockeyed. Other than that it worked fine.

I recently picked up a 10-pack of Smraza SG90 9G Micro Metal Servos for my DIY robotics projects, and my experience has been a bit mixed. On the positive side, the servos that did work delivered the expected torque and responsiveness, allowing for accurate and stable control. They integrated well with my Arduino setup and seemed to hold up under moderate loads, achieving the advertised 9 grams of force without issues.However, the biggest disappointment was that 4 out of the 10 servos were defective right out of the box. That’s a pretty high failure rate, and it’s frustrating when nearly half of the set is unusable. The functioning units are reliable and do exactly what I need, but the quality control concerns make me hesitate to recommend them without reservations.If you’re lucky and all of them work, these servos can be great little helpers in various projects. But the risk of receiving multiple defective units is something to keep in mind if you’re considering this 10-pack.

I used these on my first fixed-wing build, a Sky Surfer X8. The servos fit perfectly, and worked just fine on the first attempt. They have lasted at least 10 flights so far with no issues running on my 3S battery setup with an X8R Frsky receiver. Can't beat the price, plus you get some spares incase one does go bad.

Commercially available switches for my N scale turnouts were $20 each and up. Because of the thickness of my base, the switches needed to be modified to work. The Smraza servos did the job for $1.95 each on average. I coupled that with an Arduino micro controller for $14 and used that to power 5 turnouts. So for less than the cost of two turnouts using the commercial switches, I can drive ten. It took a little bit of engineering, but the solutions were simple and the results exactly what I needed. As a side note, I tested everything first on a small board duplicating the table base thickness. I discovered that I could use one of my iPhone's external back up batteries to drive the Arduino freeing me from a computer or USB charger to test my work. Made working and maneuvering easy. Plan to buy more servos to automate other actions on my layout.
