2. Comparison of popular image transmission systems assembled in F450
According to actual measurement data from recent technology forums, the following are the three most popular image transmission solutions:
| Model | Transmission distance | delay | Power consumption | reference price |
|---|---|---|---|---|
| Rush Tank II | 5km | 30ms | 800mW | ¥580 |
| Eachine TX805 | 3km | 50ms | 600mW | ¥320 |
| TBS Unify Pro32 | 8km | 25ms | 1W | ¥850 |
3. Assembly suggestions and techniques
1.Antenna selection: It is recommended to use a mushroom antenna or a flat antenna, which can increase the transmission distance by 20%-30%.
2.Power supply solution: Most video transmission systems support 7-24V wide voltage input and can draw power directly from the flight controller.
3.Heat dissipation treatment: High-power image transmission requires the installation of a heat sink to avoid performance degradation caused by long-term operation.
4.Frequency band selection: In the 5.8G frequency band, it is recommended to avoid the commonly used channels 1-8 and choose Raceband to reduce interference.
4. Recent price trends of popular accessories
| Accessory type | Average price change | Popular models |
|---|---|---|
| Image transmission transmitter | ↓5.2% | Rush Tank Series |
| FPV camera | ↑3.8% | Foxeer Predator |
| receiver | Basically the same | RapidFire |
| antenna | ↓8.5% | LumenierAXII |
5. Technology Trend Forecast
1.Popularization of digital image transmission: The price of DJI HD systems continues to drop, which may impact the traditional analog video transmission market.
2.Integrated design: The new generation of flight controllers begins to integrate image transmission control functions to simplify wiring complexity.
3.regulatory impact: Some areas have begun to restrict the use of high-power image transmission. It is recommended to pay attention to local policies.
4.Open source ecosystem: The cheap image transmission solution based on ESP32 has gained attention in the open source community.
6. Frequently Asked Questions for Newbies
Q: How much power of image transmission is required for F450 assembly?
A: Generally, 600mW is enough for use within 2km, and 800mW or more is recommended for longer than 3km.
Q: What should I do if the video transmission signal is interfered with?
A: You can try changing the frequency band, using high-quality feeders, or upgrading to a diversity receiving system.
Q: How to judge the quality of image transmission?
A: Key observations: 1) Snowflake level 2) Delay 3) Signal recovery speed 4) Anti-interference ability.
From the above analysis, it can be seen that the self-assembled F450 paired with a suitable image transmission system is still one of the most cost-effective FPV solutions. It is recommended that users choose the most suitable configuration solution based on actual needs and budget.
