Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Vehicle does not respond to remote control. | Low battery in vehicle or remote; not bound correctly; power switch off. | Charge vehicle battery; replace remote batteries; re-bind remote; ensure power switches are ON. |
| Short run time. | Battery not fully charged; old battery; aggressive driving. | Ensure full charge; consider replacing battery; drive less aggressively. |
| Vehicle pulls to one side. | Steering trim not adjusted; damaged steering components. | Adjust steering trim on remote; inspect steering assembly for damage. |
| Motor runs but wheels do not turn. | Damaged gears or drivetrain components. | Inspect gears and drive shafts for damage. Replace as necessary. |
