Looking at the way that battery connector is spliced and taped onto the ESC, I don't know if that truck would "safely" run anything. Those electronics don't look to be the highest of quality either. If I were you I'd buy a new 3S Senton from a reputable hobby dealer, or you can get a roller and build one yourself. Seeing as how you're new to the hobby I wouldn't necessarily recommend that second option. If you do buy used, make sure it's a Senton that came brushless/3S from the factory.
