2. Maklumat Keselamatan Penting
AMARAN: The VTX is set to 25mW by default. Power levels above 25mW require a HAM license or must be approved by local authorities. Always ensure you are flying legal frequencies and use the appropriate Betaflight VTX tables according to your region's regulations.
- Always read the instructions for proper wiring before connecting the VTX. Incorrect wiring can cause damage.
- Ensure the antenna is properly installed before powering on the VTX. Operating without an antenna can significantly shorten the module's lifespan.
- Sahkan voltage range (7-34V DC) and polarity (positive/negative) before applying power to prevent component damage.
- When installing the VTX, ensure sufficient space around the module for air convection to facilitate proper heat dissipation.
- Failure to provide adequate cooling may cause the module to activate overheat protection, leading to reduced power transmission or complete shutdown.
3. Panduan Persediaan
Wiring and Port Connections
The BLITZ Whoop VTX features clearly labeled ports for easy integration into your FPV system. Refer to the diagram below for correct connections.
Rajah 3.1: Bawah view of the VTX showing port connections.
| Label Pelabuhan | Penerangan |
|---|---|
| VBAT | Positive input for 2-8S (7-34V DC) battery voltage. |
| GND | Negative ground connection. |
| IRC | IRC Tramp Signal Input for VTX control from flight controller. |
| Video masuk | Video signal input from your FPV camera. |
| Camera out | Camera video output (if applicable for pass-through). |
| 5V keluar | 5V jldtage output for powering peripherals like an FPV camera. |
| Kamera masuk | Camera video input (alternative to 'Video in' depending on setup). |
Melekap
The VTX has a mounting pattern of 25.5x25.5mm with Φ1.6mm holes. Ensure secure mounting using the provided screws. It is crucial to leave adequate space around the VTX for air circulation to allow the integrated cooling fan and CNC casing to dissipate heat effectively. This prevents the VTX from entering overheat protection mode.
4. Arahan Operasi
Kefungsian Butang Kuasa
The VTX features a 'Power' button to control its output power and PIT mode. Refer to the image below for button location.
Rajah 4.1: Sisi view of the VTX showing the 'Band/CH' and 'Power' buttons.
- Tekan dan tahan selama 2 saat: Enters or exits PIT mode. A solid green LED light indicates that PIT mode is active.
- Tekan pendek: Changes the output power level. The number of green LED flashes indicates the current power setting:
- 1 flash = 25mW
- 2 flashes = 400mW
- 3 flashes = 1000mW
- 4 flashes = 2500mW
Band and Channel Button Functionality
The 'Band/CH' button allows you to cycle through the available bands and channels. Refer to Figure 4.1 for button location.
- Tekan pendek: Switches the channel. The number of blue LED flashes indicates the current channel (1 to 8 for 4.9Ghz, or 1 to 40 for 5.8Ghz depending on the selected band).
VTX Telemetry (IRC Tramp)
The BLITZ Whoop VTX supports IRC Tramp telemetry, allowing you to configure VTX settings directly from your flight controller's OSD (On-Screen Display) or Betaflight configurator. Connect the IRC pin on the VTX to a UART TX pad on your flight controller and configure the UART for VTX (Tramp) protocol in Betaflight.

6. Penyelenggaraan
To ensure the longevity and optimal performance of your iFlight BLITZ Whoop VTX, follow these maintenance guidelines:
- Jaga kebersihan: Regularly inspect the VTX for dust, dirt, or debris, especially around the cooling fan and heatsink fins. Use a soft brush or compressed air to gently clean these areas.
- Pastikan Penyejukan yang Betul: Always ensure that the VTX has adequate airflow during operation. Avoid enclosing it in tight spaces without ventilation, as this can lead to overheating and performance degradation.
- Sambungan Antena: Periodically check the MMCX antenna connection to ensure it is secure. A loose connection can lead to poor video quality and potential damage to the VTX.
- Periksa Pendawaian: Before each flight, visually inspect all wiring connected to the VTX for any signs of wear, fraying, or damage. Replace any damaged wires immediately.
7. Penyelesaian masalah
This section addresses common issues you might encounter with your iFlight BLITZ Whoop VTX.
| Masalah | Kemungkinan Punca | Penyelesaian |
|---|---|---|
| No video signal or very poor range | Antenna not connected or damaged; Incorrect channel/band; VTX in PIT mode; Overheating. | Ensure antenna is securely connected. Verify VTX channel/band matches receiver. Check if VTX is in PIT mode (solid green LED) and exit if necessary. Ensure adequate cooling. |
| VTX gets excessively hot, power output reduces or shuts off | Insufficient airflow/cooling; Operating at high power in confined space. | Ensure proper ventilation around the VTX. Consider reducing power output if operating in a hot environment or with limited airflow. |
| VTX does not power on or components are damaged | vol. salahtage input; Reverse polarity; Short circuit. | Double-check all wiring for correct voltage (7-34V) and polarity before connecting power. Inspect for any short circuits. If components are burned, the VTX may need replacement. |
| Cannot change VTX settings via Betaflight OSD | IRC Tramp not configured correctly; Wiring issue to flight controller. | Verify the IRC pin is connected to a UART TX pad on your flight controller. Ensure the correct UART is enabled for VTX (Tramp) protocol in Betaflight configurator. |
