DC Motor Speed Controller Board Module PWM 48V 20A βΉ549.00 The 3.3GHz Uncluttered Spectrum Finding a clean video channel is increasingly difficult in modern FPV. Operating strictly in the 3170-3470MHz frequency band, this VTX steps completely outside the noisy 2.4GHz Wi-Fi and crowded 5.8GHz FPV bands. This mid-tier frequency provides a brilliant balance—offering significantly better physical object penetration than 5.8GHz, without the massive antenna sizes required for 1.3GHz setups. It is the perfect spectrum for dedicated long-range and commercial drone operators.
Staggering 4W (4000mW) Output & Power Consistency This VTX guarantees a locked-in video feed miles beyond standard analog systems by outputting a massive 4000mW (36dBm typical) at its maximum setting. To ensure reliability, it features highly efficient Power Amplifier (PA) and power calibration, which guarantees power consistency across all 16 available channels. Pilots can select from 5 distinct power levels to suit their environment: PIT mode (-28dBm), 25mW (14dBm), 200mW (23dBm), 1000mW (30dBm), and 4000mW (36dBm).
Thermal Armor & Centrifugal Cooling Transmitting 4 Watts of continuous RF energy generates severe localized heat. To prevent thermal throttling, the VTX relies on an aluminum alloy three-layer shell structure. Nestled inside this CNC-machined housing is a large centrifugal fan that pulls high-velocity air across the internal circuitry, providing sufficient heat dissipation to ensure stable output of transmitting power during grueling, hours-long flights.
Clean RF Environment (PLL Circuit) High-power video transmitters can sometimes drift off their designated frequency, bleeding noise into other bands. RUSHFPV eliminates this by utilizing a customized digital PLL (Phase-Locked Loop) circuit. With chip-level integration, this VTX experiences absolutely no frequency drift, ensuring your signal stays exactly where it belongs and your control links remain interference-free.
Specifications

Key Applications and Projects
Fixed-Wing Long Range: Providing a heavily reliable, interference-free video link for large FPV flying wings executing 30km+ autonomous waypoint missions.
Commercial Inspection Drones: Guaranteeing flawless video feeds when inspecting dense infrastructure where standard 5.8GHz signals fail.
UAS Search and Rescue: Utilizing the uncluttered 3.3GHz band to maintain critical visuals in complex, high-interference urban environments.
Unlock New Capabilities (Project Evolution) The Dedicated 3.3G Mountain Relay: Take your long-range game to professional heights. Build a dedicated ground-station relay box! Mount a high-gain 3.3GHz directional antenna on a tripod tracking station and connect it to a dedicated 3.3GHz VRX. Power this RUSHFPV 3.3G 4W VTX directly from a 6S battery on your drone, routing the IRC Tramp wire to your flight controller for remote adjustments. Because 3.3GHz is so rare in consumer electronics, you will experience a noise floor of virtually zero, unlocking crystalline analog video at unprecedented distances!

Q: What is the operating frequency band of this VTX? The transmitter operates in the 3170-3470MHz frequency band. Note: Customizations for Band C (3010-3150MHz) and Band D (2850-2990MHz) are possible from the manufacturer.
Q: Can I use this with my standard 5.8GHz FPV goggles?No. You must install a dedicated 3.3GHz Video Receiver (VRX) module on your FPV goggles or ground station to intercept this signal.
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 VTX 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 flight controller's VBAT pads and wiring can handle this current load.
Q: What happens if I power the VTX 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 RGB lighting; long press to enter settings, then use short presses to adjust the blue (band), red (channel), and green (power level) 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. When there is no operation, the RGB LED blinks cyclically; when the green LED is always on, the VTX has entered PIT MODE.
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 without overwhelming other nearby video feeds.
Q: What kind of antenna connector does it use? It uses a standard SMA 50 Ohms threaded connector.
Q: Is the cooling fan always on? The VTX utilizes a large centrifugal fan to provide sufficient heat dissipation. Given the extreme 4W power, active cooling is necessary to ensure stable output.
Q: Does the VTX 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 VTX? 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 VTX 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, transmitting on 3.3GHz at 4000mW strictly requires an active Amateur Radio (HAM) license or specialized commercial exemptions.
Q: What is the operating temperature range? The module is rated to operate safely in environmental temperatures ranging from -10°C to +70°C
