2.low latency: E-sports grade remote control pursues a control delay of less than 1ms.
3.Intelligent: AI technology is used for automatic obstacle avoidance and signal optimization.
4.Integration: A comprehensive system that integrates video transmission and control signals.
5. Frequently Asked Questions
| question | Answer |
|---|---|
| Why is my remote control distance shorter? | It may be caused by damaged antenna, low battery or environmental interference. |
| How to improve anti-interference ability? | Use frequency hopping technology (FHSS) to keep the antenna vertical and avoid WiFi dense areas |
| Can remote controls from different brands be used universally? | A matching protocol is required, and some brands use proprietary protocols that are incompatible. |
Through the above analysis, we can see that model aircraft remote control communication technology is developing rapidly, providing users with more diverse choices. Whether you are an amateur or a professional pilot, understanding the characteristics of these communication technologies can help you obtain a better flying experience.
