It’s the universal sound of a project going on hiatus. That’s why this Smraza 6-pack is basically the "adulting" version of the standard micro servo. It's cheap, it's tough, and it fixes the biggest flaw of the entry-level kits. Review: Nice tiny servos - 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. ## Features - Motor Pinion Gear & Shaft Upgraded to Metal — Our SG90 9g micro servo motor resists tooth breakage and heat deformation seen in plastic-gear units, ideal for micro robots, robot arms, RC helicopters and DIY builds using mini and small digital servos. - Quick 0.08s/60° Running Speed & 1.9 kg/cm Stall Torque,Operating Voltage: 4.8V-6.0V, across a full 180° range. Improved Dead Band: 5 µs. - Versatile Application — Works with fixed-wing and KT planes, gliders, micro-robots, robotic arms, small boats and compact RC mechanisms, delivering precise micro-servo motion for model builds. - Arduino/Raspberry Pi Ready — Simple 3-pin PWM hookup compatible with JR/FUTABA receivers. Includes servo arms and 24.5 mm leads for neat wiring in compact DIY and R/C toy builds. - Please Note — This SG90 servo requires a continuous PWM signal and a power supply capable of more than 1A starting current. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07L2SF3R4 | | Best Sellers Rank | #24,495 in Toys & Games ( See Top 100 in Toys & Games ) #11 in RC Servos | | Brand | Smraza | | Brand Name | Smraza | | Customer Reviews | 4.5 out of 5 stars 1,304 Reviews | | Item Highlight | 180°, 1.9kg·cm torque @6V, 0.08s/60° speed, 4.8–6V,metal motor gear & metal shaft for RC Airplane Robot Arm DIY Item Highlight 180°, 1.9kg·cm torque @6V, 0.08s/60° speed, 4.8–6V,metal motor gear & metal shaft for RC Airplane Robot Arm DIY See more | | Item Weight | 0.16 kg | | Manufacturer | Smraza | | Number of Items | 10 | | Part Number | S51-4-U-F | | Unit Count | 10 Count | ## Product Details - **Brand:** Smraza - **Item Weight:** 0.16 kg - **Manufacturer:** Smraza - **Number of Items:** 10 ## Images ![Smraza SG90 9G Micro Servo Motor Kit Metal Gear for Arduino RC Plane 10 Pcs | 180°, 1.9kg·cm torque @6V, 0.08s/60° speed, 4.8–6V,metal motor gear & metal shaft for RC Airplane Robot Arm DIY - Image 1](https://m.media-amazon.com/images/I/81xownH8E3L.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: What are the names of these screws?** A: Hi. The longer two screws are PA2*8(2×8mm). The another is KM2*4(2×4mm). Hope it helps you. **Q: How would the motor respond to a 5V pulse from a momentary push button?** A: Hi. Servo provides 500~2500 usec pulse signal under 5V voltage. The servo will directly rotate to the angle corresponding to the pulse value. Hope you have a good experience with our products. **Q: Has anyone used these for model train N scale Peco switches?** A: Hello. There is no prescribed use equipment, and multiple assemblies and combinations can be cited. But need to meet the required voltage conditions. When you are using the servo, the voltage needs to reach 4.8-6V, connect the signal to the servo. **Q: Do these have wires to connect to a battery pack?** A: To go to a battery pack, 5V or 4.5V, you may cut off the red wire from the 3-pin female connector and go to the plus of the battery. The orange or yellow wire must go to a PWM signal, usually from an Arduino using analogWrite. Black or brown wire goes to Arduino ground AND battery negative. ## Customer Reviews ### ⭐⭐⭐⭐⭐ BUY THIS PRODUCT *by R***T on March 9, 2026* Look, if you’ve spent any time in the hobbyist world, you know the heartbreak of hearing that crunch-grind-pop sound when a plastic-gear SG90 hits a snag.
