They were surprisingly strong and worked well with my arduino uno! It was compatible with it. They were also fast at going to the proper degrees Review: BUY THIS PRODUCT - 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. 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. ## 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 | B09Y55C21K | | Best Sellers Rank | #33,954 in Toys & Games ( See Top 100 in Toys & Games ) #23 in RC Servos | | Brand | Smraza | | Brand Name | Smraza | | Customer Reviews | 4.5 out of 5 stars 1,305 Reviews | | Item Dimensions W x H | 1.25"W x 1.18"H | | Item Weight | 9 g | | Manufacturer | Smraza | | Material | Metal | | Material Type | Metal | | Model | S51-4-U-F | | Model Name | S51 | | Part Number | S51-4-U-F | | Product Dimensions | 1.25"W x 1.18"H | | Shaft Diameter | 5 millimeters | | Speed | 7 rpm | | Voltage | 6 volts | ## Product Details - **Brand:** Smraza - **Model Name:** S51 - **Product Dimensions:** 1.25"W x 1.18"H - **Speed:** 7 rpm - **Voltage:** 6 volts ## Images ![SG90 9G Micro Servo Motor Kit Metal Gear for Arduino RC Plane 4 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/81k+Id2F7mL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Can these be run at a higher pwm frequency than 50hz? ideally i'd like to run them at 200hz.** A: No need to think about that. These Micro Servos are not reliable. I had on fail (sticks) on me during preflight so I switched it from the elevator to rudder. Then on the next flight the elevator servo and one aileron servo failed in flight. Was lucky to get help from an experienced RC plane flyer who was helping me with the test flights. Will not buy again ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works well *by K***N on May 24, 2026* All work perfectly with no problems! They were surprisingly strong and worked well with my arduino uno!
