Attention: The VTX800 supports up to 1600 mW, and it is recommended to set it to 800 mW for extended use. The factory default setting is 800 mW. Before powering on, ensure the antenna is securely connected; failure to do so may cause damage. The VTX800 generates heat during operation, which is normal. Avoid touching it while powered on. Higher output power results in increased heat generation. The PCB is made of high-quality materials designed to withstand elevated temperatures without damage. Install the VTX800 away from flight controllers and in a well-ventilated location on the aircraft. For optimal thermal management, orient the heatsink upward and ensure airflow around the unit. Supports manual adjustment of power and frequency, and OSD parameter adjustment via IRC protocol. Model: VTX800 Frequency: 5645–5945 MHz Input Voltage: 7–26 V Output Voltage: 5 V / 1 A Channels: 40 Transmission Power: PIT / 25 / 200 / 400 / 800 / 1600 mW Color: As shown Material: PCB Package Contents: 1 × VTX800 Board Set Other items are not included. Note: Color variations may occur due to lighting conditions and display settings. Slight dimensional variations of ±1–3 cm may occur due to measurement methods.
