hey:) I am working on that same project with a friend, when we found your video. We would love to see your blueprints etc. but unfortunately the link in the video description does not work.
I looked through the project documentation and there is nothing about the breaking system. The real constructed examples have breaks. Breaks are needed for a trailer this size and with a significant amount of weight. The empty trailer is already heavy. it would be dangerous to use this with cargo without a breaking system.
No hay costo por estos planos, el enlace para descargar, está en la descripción del video. Próximamente estaremos publicando un caso real, con planos actualizados
