So i bought a brand new slash roller off ebay and used my motor esc and reciever from my rustler vxl. I just recently bought a tqi (3ch) with docking base and ever since then my rustler wasnt going as fast, so i thought it was my battery so i got a battery for my slash 4x4 and it was a 3s and my friend has a 2s and it is movin faster. also the brakes on mine are terrible and it overheats alot. could it be my esc, motor, reciever, transmitter, or since my phone is still setup to be linked to my rustler. it is not on training mode either. im gonna sync my slash to my phone and set it all up tmrw, but any suggestions PLEASE HELP!!!!!!!
