This is my SC10 4x4, it has a CC 3800 kv motor and CC mamba max pro esc. I use a Savox 1256 TG servo. There are RPM A arms on all four corners. I also have a few STRC aluminum goodies on it such as the wheel hexs, motor plate and front and rear toe blocks (A arm mounts). On board there is also the carbon fiber chassis brace, VTS 3 pad slipper clutch.
