5. Operating Instructions
Operating your ARRMA Typhon GROM requires attention to safety and proper control techniques.
- Power On: Turn on the transmitter first, then the vehicle's power switch.
- Throttle Control: Use the trigger on the transmitter to control forward and reverse movement. Pull for forward, push for reverse/brake.
- Steering Control: Use the steering wheel on the transmitter to turn the vehicle left or right.
- Dynamic Stability Control (DSC): The integrated Spektrum DSC system helps maintain vehicle stability during aggressive driving. Familiarize yourself with its operation and how to adjust it if needed (refer to the full manual).
- Throttle Limiting: For new drivers or in confined spaces, utilize the throttle limiting feature on the transmitter to reduce maximum speed and improve control.
- Battery Usage: The vehicle supports both 2S and 3S LiPo batteries. A 3S battery will provide significantly higher speeds (up to 50+ mph), requiring more advanced driving skills. Always use batteries compatible with the vehicle's electronic speed control (ESC).
- Safe Operation: Always operate your RC vehicle in open areas, away from people, pets, and obstacles. Avoid public roads.
6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your ARRMA Typhon GROM.
- Cleaning: After each use, especially in dusty or wet conditions, clean the vehicle to remove dirt and debris. Use a soft brush or compressed air.
- Inspection: Regularly inspect all components for wear, damage, or loose connections. Pay close attention to suspension arms, shock absorbers, and drivetrain components.
- Fasteners: Check and tighten all screws and nuts periodically, as vibrations during operation can cause them to loosen.
- Lubrication: Lubricate moving parts as recommended in the full product manual to reduce friction and wear.
- Storage: Store the vehicle in a clean, dry place when not in use. Remove batteries from both the vehicle and transmitter during storage.

7. Troubleshooting
If you encounter issues with your ARRMA Typhon GROM, consider the following common troubleshooting steps:
- Vehicle Not Responding: Ensure both the vehicle and transmitter are powered on. Check battery levels in both the vehicle and transmitter. Verify that the vehicle and transmitter are properly bound.
- Loss of Range/Interference: Ensure no other 2.4GHz devices are operating nearby. Check for damaged antenna wires on both the vehicle and transmitter.
- Reduced Performance: Check battery charge level. Inspect for debris in the drivetrain or damaged gears. Ensure motor and ESC are not overheating.
- Steering Issues: Check for obstructions in the steering mechanism. Verify the steering servo is functioning correctly and its connections are secure.
- Unusual Noises: Immediately stop operation and inspect the vehicle for loose or damaged parts, especially in the drivetrain (gears, bearings).
