Troubleshooting[edit]

[2] The cars really only have a few parts of major interest:

  • Motor
  • Receiver box
  • Electronic speed controller box (brushless L202/L212/L222 models only)
  • Steering servo
  • Gearbox
  1. Steering but no forward/reverse: Motor burned out (replace), motor driver MOSFETs on receiver burned out; often happens due to water / snow / dirt (replace receiver), stripped gears in gearbox (replace gearbox).
  2. No steering, no forward/reverse: Car not on (turn on), transmitter not on (turn on), transmitter did not bind correctly (turn both off, then both on), car or transmitter batteries dead (replace), receiver module defective (replace), transmitter unit defective (replace).
  3. Forward and reverse are backwards (usually brushless L202/L212/L222): Swap any two wires on the ESC unit
  4. Car stops suddenly: Battery is dead (car stops automatically to avoid overdischarge), broken receiver (replace), radio reception is poor (reorient antenna), transmitter batteries weak/dead (replace batteries), stripped gears in gearbox (replace gearbox).
  5. Car runs for 1 minute or less and stops, turning off and on will repeat: Battery is dead (recharge battery)
  6. Forward/reverse, no steering: Steering servo broken (replace)
  7. Car moves forward/backward without trigger being moved: Transmitter trim is out of adjustment (adjust via trim buttons), receiver FET dying and allowing current when off (replace receiver)
  8. Forward and steering, no reverse: Transmitter trim out of adjustment such that the car is actually in forward gear without actually moving; when car is in forward gear, reverse cannot be engaged (fix via transmitter trim buttons).
  9. Car drifts to one side: Road is curved/crowned to one side (i.e. car follows the slope), transmitter trim is out of adjustment (use trim buttons), front tires out of alignment (steering arm can be moved in/out to different points by removing/replacing screw)
  10. Car flips on cornering: Rear tires set too far in, car is no longer stable (move rear tires out via spacers, fatter tires, or lowering shocks). (Note: not usually an issue with stock setup and tires.)
