Kimpok Analog Transmitter KP-T33A10

Kimpok KP-T33A10 Analog Video Transmitter – 3.3 GHz VTX with up to 10 W Output Power

Kimpok KP-T33A10 is a high-power 3.3 GHz analog FPV video transmitter designed for advanced hobby builds where strong signal, stable transmission, and effective cooling really matter. With up to 10 W output power, 16 channels across two bands, adjustable power levels, Pit Mode, and IRC Tramp control, this VTX is a solid choice for demanding FPV setups and long-range projects.

Built for more challenging configurations, the Kimpok KP-T33A10 features an aluminum housing, heatsink, and cooling fan to help manage heat during high-power operation. Its wide DC 15–36 V input range supports 4S to 8S batteries, making it easy to integrate into a variety of custom FPV platforms.

• 3.3 GHz analog FPV VTX for advanced hobby and long-range applications
• Maximum output power: 10 W
• 5 selectable power levels: 1 W / 2.5 W / 5 W / 7.5 W / 10 W
• 16 channels across Band A and Band B
• IRC Tramp support for easy flight controller integration
• Pit Mode for safer bench setup and pre-flight configuration
• Active cooling with fan and heatsink
• Wide input voltage: DC 15–36 V, compatible with 4–8S packs

Up to 10 W Output Power with 5 Adjustable Levels

The KP-T33A10 gives you five power levels, so you can match the transmitter output to your flying conditions, antenna setup, range requirements, and local radio regulations. Lower settings are ideal for testing and short-range flights, while the full 10 W mode provides serious signal headroom for more demanding FPV use.

• 1 W – great for short-range flights and bench setup
• 2.5 W – balanced output for stable video and moderate power draw
• 5 W – high-power mode for more challenging FPV environments
• 7.5 W – extra signal reserve for longer flights
• 10 W – maximum output for long-range applications
• Pit Mode – useful during setup, testing, and working on the model before takeoff

3.3 GHz Band and 16 Transmission Channels

The Kimpok KP-T33A10 operates in the 3170–3470 MHz range and offers 16 channels split across two bands. Each band includes 8 channels, giving you the flexibility to match your receiver and choose the frequency that works best in your specific FPV setup.

Channel selection is quick and easy using the Band & Channel button. A red LED indicates the selected channel by the number of flashes, while a longer press switches between bands. A blue LED shows whether Band A or Band B is currently active.

IRC Tramp Support and Simple Button Control

The KP-T33A10 supports IRC Tramp, making it easier to integrate with a flight controller and manage VTX settings in a more convenient way. This is especially handy when the transmitter is mounted deep inside the frame and direct physical access is limited.

The module includes dedicated buttons for band, channel, and power adjustment. Clear LED indicators make it easy to check current settings without connecting a computer: red for channel, blue for band, and green for power level or Pit Mode status.

• IRC Tramp support for flight controller integration
• Band & Channel button for fast frequency changes
• Power button for switching output levels
• Hold the Power button for 3 seconds to activate Pit Mode
• LED indicators for quick status checks in the field

Aluminum Housing, Heatsink, and Active Cooling

Running at up to 10 W requires efficient thermal management, and that’s exactly what the KP-T33A10 is built for. Its aluminum case, heatsink, and built-in fan help maintain stable performance during longer sessions and at higher power settings.

The transmitter also includes thermal protection. If the module temperature exceeds 100°C, the output power is automatically reduced by one level. If the temperature remains too high, the power continues to step down until it reaches the lowest setting. Once the module cools to around 95°C, the transmitter returns to the previously selected power level. Even with this protection, proper airflow around the housing is still essential.

What’s Included and Usage Notes

The package includes 1 x Kimpok KP-T33A10 analog video transmitter. The antenna, wiring, and mounting accessories should be selected to match your specific FPV build, receiver, and intended operating range.

• Kimpok KP-T33A10 3.3 GHz 10 W analog VTX – 1 pc

Always connect an antenna to the SMA port before powering on the transmitter. Do not run the VTX without an antenna, as this may shorten the module’s lifespan or permanently damage it. Before applying power, double-check the voltage range, wire polarity, video signal wiring, and IRC connection. Install the transmitter with enough free space around the housing to ensure proper airflow and effective cooling.
