Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No power/Transmitter won't turn on | Low or dead batteries; Incorrect battery installation. | Replace batteries with fresh ones; Ensure correct polarity. |
| Unstable battery indicator / Rapid battery drain | Poor quality batteries; Loose battery connection. | Use high-quality AA batteries or a compatible rechargeable battery pack; Ensure batteries are seated firmly. |
| No response from vehicle | Receiver not bound; Receiver not powered; Incorrect wiring. | Perform binding procedure; Check receiver power connection; Verify all wiring is correct. |
| Steering/Throttle glitching or erratic behavior | Interference; Loose servo/ESC connection; Incorrect channel phase; Faulty servo/ESC. | Operate in an area with less interference; Check all connections; Adjust channel phase in transmitter settings; Test with different components if possible. |
| Difficulty with advanced settings | Unfamiliarity with menu; Firmware issue. | Refer to the "Operating Instructions" section and practice navigation; Consider updating firmware if issues persist. |
