Neither motor works when powered with 12v. This is with nothing attached to the motor.

Fast but completely without any strength. Speed is irrelevant . Not worth the expense

The GA12-N20 gear motors are compact and versatile, making them a good pick for small DIY projects where space and weight are important. I used these in a 3D-printed RC forklift project, and while they worked well for the most part, there are a few things you should know before deciding if they’re the right fit for your build.How I Used Them in My RC ForkliftIn my project, I needed two motors—one to power the forklift’s wheels and another to operate the lifting mechanism. These motors (3V, 100RPM) were a great match for the size and weight of my build. The low RPM gave the forklift a more realistic, controlled movement, and the torque was strong enough to handle small loads (like lifting screws or LEGO bricks).That said, I did notice that these motors can struggle if you push them too hard. For example, when I tried lifting something heavier, like a small metal part, the motor stalled. I also had to make sure the wheels and gears were aligned properly because these motors aren’t very forgiving with excessive strain.What I LikedCompact Size: These motors are tiny and fit perfectly into my RC forklift design without making it bulky.Good Torque for Small Loads: They’re great for light-duty tasks like moving small RC vehicles or operating lightweight mechanisms.Affordable: You get two motors in one pack for a decent price, which is nice if you’re experimenting with multiple projects.What I Didn’t LikeLimited Power: If your project involves anything heavy, these might not cut it. The motors struggled when I tried lifting loads heavier than 200g.Noisy at Higher Speeds: When I ran the motor at 6V instead of 3V to test higher speeds, they got pretty loud.Durability Concerns: After a few hours of continuous use, I noticed the motor casing gets warm, so I wouldn’t recommend running them for long periods without breaks.Other Ideas for UseBesides the forklift, I can see these motors working well in other small projects. For example:A line-following robot that doesn’t need a lot of speed.A motorized toy car or a smart car chassis.A small conveyor belt for tabletop automation projects.

Both motors were given 12V like the description said they could handle. They were placed into a robot for a competition for school. Both motor gearboxes stripped, and the final gear is missing some teeth! The backlash kept growing and growing during testing till they both failed under 3 hours of testing. I added grease to the other one after the first failure and it still blew. Now I have a dead robot two days before a competition. Oh well......
