1. Speed control in Training Mode
    Set ESC to operate in Sport Mode for 100% throttle operation. Refer to manual for details.
  2. Under geared
    Install a larger pinion gear (more teeth).
  3. Transmitter throttle trim adjustment is not set correctly
      Set the throttle trim knob to zero and recalibrate your speed control.
  4. Burned out resister or speed control (mechanical speed controls only)
    Visually inspect the resistor - if it's cracked or discolored replace it with a new one. If the resistor looks fine, you'll need to replace the mechanical speed control. The mechanical speed control includes a new resistor just in case.
  5. Electronic speed control incorrectly set up
    Follow the ESC set-up instructions in your vehicle's owners manual to properly set the throttle's neutral and end points.
