RUSHFPV 1.3G 4W Image Transmission V2 - 16CH Extreme Long Range VTX with Centrifugal Cooling

FREQUENTLY ASKED QUESTIONS (FAQ)

Q: What is the operating frequency band of the V2 Image Transmission module? The transmitter operates in the 1080-1360MHz frequency band.

Q: Can I use this with my standard 5.8GHz FPV goggles? No. You must install a dedicated 1.3GHz Video Receiver (VRX) module on your FPV goggles or ground station to intercept this signal.

Q: Will this 4W transmitter interfere with my drone's GPS module? High power can cause interference, but the V2 features a built-in bandpass filter specifically designed to reduce harmonic interference to navigation equipment. However, physical separation between the VTX antenna and GPS is still highly recommended.

Q: What is the maximum power output? The maximum output is power level 4, which is 4000mW (4 Watts).

Q: What input voltage does the module require? It requires a DC power supply between 7V and 30V (labeled 7-30V Lipo-IN).

Q: Can I power this directly from my 6S battery? Yes. A fully charged 6S LiPo is 25.2V, which falls safely within the 7-30V input range of the VTX.

Q: How much current does it draw at maximum power? At 4000mW, it draws approximately 1400mA at 12V. You must ensure your wiring and power pads can handle this current load.

Q: What happens if I power the module without an antenna attached? You will destroy the amplifier circuitry. The manufacturer explicitly warns that the antenna must be connected before use, otherwise there is a risk of damage to the product.

Q: How do I change channels manually without a flight controller? You can use the single onboard button. The button integrates an RGB LED; long press to enter settings, then use short presses to adjust the blue (band), red (channel), and green (power) values.

Q: Does it support remote OSD control via Betaflight/INAV? Yes. You can control it via the flight controller by connecting the DATA pin and utilizing the IRC Tramp control protocol.

Q: How do I enter PIT mode? PIT mode can be selected via OSD/Tramp, or manually via the button. In PIT mode, the power LED (green) remains always on.

Q: What does the PIT mode power level drop to? In PIT mode, the typical power output drops to -28dBm, allowing you to safely power up near other pilots without blowing out their video feeds.

Q: What kind of antenna connector does it use? It uses a standard SMA 50 Ohms threaded connector.

Q: What type of antenna is included in the box? The included transmitter antenna is a Right Hand Circular Polarized (RHCP) omni-directional antenna with 1.7dBi of gain and an RG402-SMA cable.

Q: Is the cooling fan always on? The unit utilizes a large centrifugal fan to provide sufficient heat dissipation. Given the extreme 4W power, active cooling is critical to ensure stable output.

Q: Does the module provide a 5V output for my FPV camera? Yes. The 6-pin wiring harness includes a dedicated 5V output pin specifically to power external analog cameras.

Q: How stable is the frequency on this V2 unit? It is extremely stable. It utilizes a customized digital PLL (Phase-Locked Loop) circuit with a frequency stability of ±100KHz (Typ.), resulting in absolutely no frequency drift.

Q: How many channels does this support? It supports 16 custom channels spread across Band A and Band B.

Q: Do I need an amateur radio license to use this? In almost all jurisdictions (including the US and Europe), transmitting on 1.3GHz at 4000mW strictly requires an active Amateur Radio (HAM) license.

Q: What is the operating temperature range? The module is rated to operate safely in environmental temperatures ranging from -10°C to +70°C.
