Miuzei MG90S 9G Micro Servo Motor Metal Gear for RC Plane Robot Arduino (4)

I bought these to replace standard sg90's with plastic gears. These are strong, silent and super smooth. I recommend and will buy again.

I ordered 10, servos work as they should. Package arrived really quick. I use them for robots for simple jobs like moving their antennas or something that isn't to demanding.

I used these to replace the terrible Spektrum A330 servos that came in my Eflite Pitts 850mm plane. So far I have replaced the aileron servos and plan to swap rudder and elevator as well. They were a direct fit into the pockets in the wings. I found they are 2 grams heavier than the original plastic gear servo. They are much quieter than the plastic ones as well. I did have to reverse their travel in the transmitter. For the price they're hard to beat. Durability is yet to be seen but they can't be worse than the original and are a fraction of the price.

Perfect upgrade

Every servo worked as advertised/functioned perfect

Exellent metal gear micro servos specially for small helicopters like the 450 align

Garbage. They don’t lift what they are rated for. Very weak. Gears are made from powdered metal, and strip very easily

First bit of servos I've ever had. I had to jam them in some Robo Sapien claws and give my robosapien head movement because I stuffed a bunch of computers in him and turned him into an oven. He's the most advanced robosapien on the planet, actually, no joke. He's got four of these bad boys in him and they don't draw too much current. Sometimes they'll bounce around trying to find their positions and the issue is only made worse by my attempts to create interpolation animation, but the fact that they're working at all is kind of mind-boggling. He's also moving his claws with them, of course I pulled the original springs out but they snap right open and closed. They're also pretty durable, I was able to hack off the bottom of two of them to shove them inside of a claw, the wires popped off and I spent a good minute boiling that servo trying to get my broad soldering iron to fix it all up, and surprise surprise it worked. This probably a reason many people buy this thing. It's redundant, it's cheap and it works well enough. Unfortunately they're pretty loud. The torque is somewhat decent, I've never had servos before though so having them outside of a stem class is fun!

Good quality and fast delivery

Great! on second season in mini Warbird. No issues, no hunting, good home position.

Good servos do the job.

For my first project into servos these small micro servos did what was intended and in a precise way. The gearing did not have any slop and is quite accurate. The build quality is as expected and works quite well with firmware in the Arduino I used.

It works well but the power on the box is miss leading it says operating voltage is 4.8 but It got pissy if It was anything higher then around 2 volts and some of the motors make a weird clicking sound (But I'm not to surprised about the clicking sound they are cheap) but other then that they are perfectly fine as far as I know
