High latency (>20ms)	USB bandwidth saturation	Use USB 3.0 ports, reduce other USB devices
Control conflicts	Improper controller assignment	Reconfigure controller mappings in RealFlight
Random disconnections	Power saving settings	Disable USB selective suspend in Windows power options
Audio stuttering	CPU overload	Reduce graphics quality, close background apps

Performance Optimization Tips

• USB Port Management:
  • Use separate USB controllers if possible (check Device Manager)
  • Avoid using USB hubs – connect directly to motherboard ports
  • For laptops, use ports on different sides (often different controllers)
• Windows Settings:
  • Set power plan to “High Performance”
  • Disable USB selective suspend: Control Panel > Power Options > Change plan settings > Change advanced power settings > USB settings
  • Update all USB controller drivers
• RealFlight Configuration:
  • Reduce graphics quality to “Medium” or “Low” for multi-transmitter setups
  • Disable unnecessary visual effects (water reflections, advanced shadows)
  • Limit physics complexity for secondary models
• Hardware Considerations:
  • Use USB 3.0 or higher ports for all transmitter connections
  • Consider a USB PCIe expansion card if your motherboard has limited ports
  • For wireless connections, maintain line-of-sight to dongles

Advanced Configuration Options

For experienced users looking to push their dual-transmitter setup further:

• Custom Control Profiles:
  • Create separate control profiles for each transmitter
  • Use RealFlight’s profile system to quickly switch between configurations
  • Experiment with different control mixes for specialized training
• Networked Multi-PC Setup:
  • Connect two PCs via LAN for distributed processing
  • Use one PC for physics/control, another for graphics
  • Requires advanced networking knowledge and RealFlight’s network features
• Custom Scripting:
  • Use AutoHotkey or similar tools to create macros for quick transmitter switching
  • Develop custom training scenarios with automated transmitter hand-offs
  • Create performance monitoring scripts to log latency and frame rates
• Hardware Modifications:
  • Build custom USB isolators to reduce electrical interference
  • Create physical mounting solutions for ergonomic dual-transmitter use
  • Develop custom LED indicators for active transmitter status

Safety Considerations

While setting up multiple transmitters can enhance your simulation experience, it’s important to consider safety aspects:

• Physical Safety:
  • Ensure transmitters are securely mounted to prevent drops
  • Keep antennae away from eyes and face during operation
