It is a perfect fit for my Mini airplanes and control arms are perfect. Great all around!

Bought the box of five... they arrived quickly. I tested all and they all worked. There is a fair amount of difference between them in the sound they make, with some of the gear-trains being quite noisy... but there seems to be no difference in function. Travel was fairly uniform between them, and position repeatability was adequate for what I'm using them for. They are not the "quickest" of servos. These will all be going in sub 250 gram casual fixed wing fliers and in that application these will be just fine. As someone that has been in this hobby for 50+ years, I'm amazed at how far down the price curve RC gear has come.

Small size has strong movement and works great with my 36 inch wing surfaces.

For those who don't already know, the 3.7g rating refers to the weight of the servo itself with no wires or servo arm. This doesn't make a lot of sense, because you can't use the servo without the wires and servo arm. This is normal for most servos listed as 3.7 grams. My scale put these at 4.96 grams. Very small and compact.

I thought these would be great for my RC glider project to keep the weight down. High torque was not required. But out of the pack... one of the 5 did not work. Out of the 4 left, one moved jerkily, so picked 3 others that moved smoothly. Installed those into the glider.. they are quiet until screwed down, then get very noisy, not even tightly screwed into place. Then within the first session trying out the glider for about 1 hour... 1 servo is still good, 1 is now sticky movement, and one stripped its own gears and does not work anymore. Yes they are light weight... but... very weak and are either broken on arrival or broken quickly once they are used. Next time I will buy servos with metal gears instead of plastic.
