COMMENTS

If powering the vehicle with a 2S LiPo battery, the jumper on the
ESC MUST be set to LiPo mode.
Face the side of the ESC with the Battery Mode Indication Sticker
Place the jumper across the center and left pins when viewing this
sticker.

*Some aftermarket batteries may require the removal of the Battery
Mounting Block for proper fit. This can be accomplished by
removing the 3x12mm screw that threads through the chassis and
mounting block.
