Review: Es muy pesada, no se si eso equivale a solidez pero da esa sensacion de que estas controlando una maquina bastante potente y capaz, ya con baterias son 7.5KG que se pueden mover bastante rapido por lo que hay que tener cuidado. Cuando un RC deja marcas de llanta en el pavimento sabes que estas en el lugar correcto.
Review: Comparing the Big Rock 6s to my modified Granite, it’s a lot easier to control and is faster & more fun to use. I didn’t even want to use it since it looks so nice. It’s sad that Arrma discontinued this r/c car. Get it while you can before they’re all gone.
