TROUBLESHOOTING

Here are some helpful tips to address some common problems.

Car turning sharply in one direction and not the other

  • The pinion gear may be touching the tire
  • Check that the front pair of tires are the same diameter
  • Check that the rear pair of tires are the same diameter
  • Check that the front pair of wheels match
  • Check that the rear pair of wheels match
  • Check that front tires aren’t rubbing light buckets
  • Check that rear suspension movement isn’t hindered
  • If it turns sharply to the left and you’re using a stock diff, check that the left rear wheel nut isn’t too tight.

Car unable to move but the servo motor still works to turn the wheels

  • Check that the pinion gear is able to turn the spur gear
  • Check that the motor wires are connected to the main board
  • Check that the motor wires are connected to the motor
  • Check that the capacitors are correctly soldered to the motor
  • Check/reset transmitter throttle, acceleration, and boost settings
  • Attempt transmitter reset
  • Can you move in one direction and not the other?
    • Check/reset transmitter throttle, acceleration, and boost settings
    • Potentially blown fets on the board due to overstressing, replace board
  • Replace the motor
    • Still not working? Replace the board

Car making terrible sounds

  • Check gear mesh
  • Try adding comm drops to motor brushes, bearing, bushing
  • Really, check gear mesh. If you want buttery smooth near silent gears, consider upgrading to 64p gears.

Transmitter Reset Directions

  1. Turn off the transmitter if it is on.
  2. Make sure that the steering trim knob is at the center position
  3. Turn the G.SPD L (speed limiter, right side) knob fully to the counterclockwise direction.
  4. Position of G.SPD H (LED control, left side) knob does not matter.
  5. Turn the steering wheel to the fully right position and push the throttle away to the full-brake position and hold them.
  6. Turn on the transmitter. The LED should flash rapidly; this means you are now in the factory mode.
  7. Release the steering wheel and throttle lever.
  8. Turn the steering wheel fully to the left, right, left and right, and then release it.
  9. Pull/push the throttle lever to full-throttle, full-brake, full-throttle, and full-brake, and then release it.
  10. Turn the G.SPD L knob to the right most position. The LED should become solid.
  11. Turn off the transmitter and on it again. You are done.
