MG90S 9G Micro Servo Motor Metal Gear for RC Plane Robot Arduino (4) | 2.0 kg.cm Torque, 0.08sec/60°Speed. 9 gram Mini Digital 180 Degree Steering Servo Kit for Helicopter Airplane Car Boat Diy

These mini servos are amazing! Their small compact size does not show low quality. I was very surprised with their capability. The small but mighty metal geared servos have very high torque for their size. They even are surprisingly quiet and quick. Being metal geared, they have way better performance than plastic geared servos of this size, but aren’t much heavier. Overall these are great high quality servos.

Perfect upgrade

Using these Servos in a EPP foam beater CrashTestHobby Albatross ~ Gets slammed into the ground and tossed in the bed of my Truck and I’ve had no issues at all!!

Servos work well but no stops at 180 degrees. Be aware the 10 pack and 8 pack have the mounting tabs in different locations

They are all metal gears. I just hope they all test good. But I bought extras just in case I get a bad one.

Work really well and are quiet appear to be good quality

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!

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.

Good quality. I can tell the are fresh cut gear still as they just had some chewing in to do but once it got past 10 or more full continuous back and forth it worked in and has lots of strength now!! Exactly match for sg90 servo upgrade. 10 servos with full set hardware individually bagged for each servo. Shame it doesn't come with that little screwdriver ;).

Good quality and fast delivery

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.

These feel really good quality, and I don't worry about having stripped gears as these have metal ones. Highly recommended.
