Review: Great setup!!! - My stepson and I put this on his Traxxas Rustler tonight and holy crap what a difference!!! Says in the instructions not to use a 3S battery but we did anyway!!! And it’s a rocket ship!!! Very nice!!!
Review: BEWARE - when i received the package the box the item came in had been opened and wires were sticking out. I inspected the item and it looked ok so I then proceeded to install the motor and esc in my RC car. Everything seemed ok the motor ran for about 1 minute then nothing it stopped working. I checked the wiring and the the connections and all was secure. My receiver was also damaged by the product. I contacted the seller and was just brushed off and was told give them 3-4 days to reply and nothing. After lmost a week of waiting for any kind of reply i just gave up desertcart returned my money to me, after about a day of contacting and still no motor no ESC nothing. Very disappointed

Really solid replacement on my rustler 2wd! Went from brushed to this and it’s so much more responsive, motor does get hot quick but for the price I easily recommend this combo
