Very solid and easy to use.By
These are very well made and are surprisingly strong for their size. They seem to be pretty precise although I haven’t really used them for applications that required precision and I haven’t tested their precision specifically. Their strength definitely surprised me though. They have metal gears so that helps. I created an arduino sketch to drive them and I held the “axle” with one hand the the rest of the motor with the other and when the motor was turning, I had a very difficult time keeping it from moving. I gave up simply because I did not want to damage the motor although It definitely withstood more torque resistance than most plastic geared servos I’ve used in the past.
