Product description
Description: the FS90R is an analog microserver that can be rotated continuously clockwise or counterclockwise without moving to a preset position. The server can be controlled using arbitrary server code, hardware, libraries, and Arduino.
It is suitable for beginners who want to move objects without using a motor controller, especially in narrow Spaces.
They may need a simple calibration to say "stop" to the servo. A small screwdriver is then used to lightly adjust the recess of the electric potential until the servo stops moving.

All 8 that I ordered passed my initial testing. I hooked up a BEC and receiver and checked each one.

I bought 6 of these for a mini sprit wing that called for this size. Using a 5V 1A BEC ESC and already had two get very hot and start melting the casing. Not binding at all in my setup. I also had the bottom come off another one as well with little handling. Disappointed and I am leery now on using the rest. Will be looking for higher quality versions. Suggest using a 1N4001 Rectifier Diode inline to the BEC power to drop down BEC voltage for any of these type of servos. Perhaps even two to get the voltage down more.

I ordered these to play with a couple small toy RC planes to see if I can make the ailerons work. They are good working little servos and should work nicely as long as my project is successful

These servos are extremely lightweight and small, fit for small control surfaces in model airplanes or other applications where a limited force level suffices. Still, for the size, these pack quite a punch, they move firmly and authoritative in position. The travel angle seems to be more limited than in full-sized servos, but that’s enough for the above-mentioned application. These surely have all-nylon, real small gears, so durability may prove to be an issue. For the price, though, I could keep a few handy as replacements at all times.

I bought these servos for use with a gyro in order to have stabilization and flight modes

I'm in the process of building a peanut scale model. These servos should fill the need and I'm looking forward to putting them in service. I've run initial tests without problems, so all looks good so far. Since they're not the recommended servos for the model I'm building, it may take some cut and try.

This servo fall to pieces relatively easily. If your delicate with it, it can be worked with. The total throw doesn't seem to be more than 45 degrees though. I wish it had a little more...
