Start Building 3DOF

Good afternoon to all members, I'm new to the community, but I've already read some projects.. I'm starting to buy the materials to start my project, I'm a web developer where I work with nextjs, sql data etc.. but I understand little about this electronic programming, arduino and engines...

I started buying an arduino uno board and now my main doubt is in the engines I saw some posts but I would like to know which is the best cost benefit, that it holds a good weight and a lot of hours of play.. Since I saw a Brazilian tutorial and the engines were heating up, I'm waiting for an answer, thank you!!

Show by example what type of simulator you want to build, then something can be suggested.

My simulator will be the same as the video, I'm thinking of using this same engine, but mine is if it lasts a lot of time using..

The only difference that would be from the video is that it would use 1 more engine below to move the simulator, simulating the car skidding

I'm in doubt about these Chinese and unbranded engines, could you give your opinion about it?

Engines from this project are ok, I also use them .
Just remember that the author wrote that in order to keep the IBT2 bridges from failing he had to lower the supply voltage to 18.5V.
If you want to use 24V supply voltage and have full power of motors it will be a good idea to change IBT2 bridges to this controller.

( I have it and have been using it successfully for a year ) or some other.
The question is in what technology you will make owj motion sim , if you have the ability or skill to weld this project is very well described.
