For long-range FPV flying, a high-power video transmitter (VTX) is essential for achieving greater range and maintaining a reliable signal. While high-power VTX models can come with a hefty price tag. The discovery of the Extremely 1.6W VTX, priced remarkably low at under $22, sparked my curiosity due to its exceptional affordability and impressive 1.6W power output, making it a highly competitive option in the market. I decided to take the plunge and give it a shot to see how it would perform.
New to FPV? Discovering the Ins and Outs of Video Transmitters: A Comprehensive Guide for Purchasers
Would you consider upgrading to a high-quality video transmitter for your drone, such as the Ultra1600 VTX from AliExpress?
As the VTX is unbranded, it can be challenging to assess the typical quality control measures in place, which may lead to a lack of support from the manufacturer or vendor if issues arise during use. One reason for its relatively low value lies in this consideration: preserve this thought as you weigh your options.
The Ultra1600 VTX’s arrival is marked by unassuming packaging, containing the module itself, a handy MMCX-to-SMA adapter cable, and a necessary harness for seamless connection to the flight controller. While the packaging itself is uncomplicated, concerns arise from the lack of a protective shield, potentially leaving items vulnerable during transit.
The Ultra1600 VTX boasts an impressive array of features, making it an attractive option for FPV enthusiasts.

Upon closer examination, it becomes evident that the Ultra1600 VTX is specifically engineered for extended-range flight operations. The VTX boasts a substantial heatsink designed to effectively manage heat generation during operation, especially when processing elevated power levels. The unit also assists the IRC Tramp protocol, enabling seamless setting control through the OSD menu for features such as channel and power levels.
The VTX is notable for its adaptability, accepting a broad range of voltages from 2S to 8S, rendering it an excellent choice for various drone configurations. The device also comes equipped with a built-in microphone that provides real-time audio suggestions; although, I haven’t had the opportunity to assess its sound quality, as it’s not a crucial feature for my aerial pursuits.
Using the equipment, I analyzed the Extremely 1W6 VTX’s power output. While the outcomes were satisfactory for a $20 VTX, the significant increase in the 25mW stage exceeded expectations, potentially posing a challenge for those seeking precise power levels. Despite its potential drawbacks, the appeal of higher energy settings is particularly pronounced for long-range flights.
While the VTX initially failed to reach its promised 1.6W output, it ultimately peaked at a respectable 1.05W maximum power. While this reading falls short of its advertised level, it still offers considerable scope. With a 9 dBi patch antenna incorporated into your goggles and a 2 dBi omni-directional antenna fitted to your quad, the anticipated range is approximately 4.5 kilometers. Compared to a genuine 1.6W VTX, which offers a range of approximately 5.5 kilometers in this scenario, the difference amounts to a mere 18% increase.

| 1600mW | 1050 | / | / | / | / | / | / | 1010 |
As outlined below is the breakdown of the ability consumption when powering the VTX at 9V:
- 0.18A (1.6W)
- 0.45A (4.1W)
- 0.68A (6.1W)
- 0.88A (7.9W)
The VTX is capable of being powered directly from the battery, thanks to its broad voltage support range of 2S to 8S. If you choose to power your aircraft from a 9V BEC connected to your flight controller, ensure that the BEC is capable of handling at least 1 ampere or more when operating at maximum output power settings.
The VTX channel, band, and energy settings can be altered by using the physical push button on the VTX. While deciphering LED blink patterns may seem an arduous process by simply counting blinks, To achieve optimal results, consider configuring VTX Management settings using the On-Screen Display (OSD) menu for customization. What sets VTX Management apart from its competitors is its commitment to delivering personalized solutions that cater to each client’s unique needs.
To configure a VTx output on your Betaflight flight controller, simply install an additional VTX module known as a VTX desk. Unfortunately, the vendor failed to provide a VTX desk, and an online search yielded no results. Despite initial doubts, I was able to figure it out. What’s the lowdown on the VTX desk? The Valco VTX desk is a portable workstation designed for photographers and videographers. Its sleek design and durable construction make it perfect for those who need a reliable workspace that can withstand the demands of the creative industry. With its adjustable height and ergonomic design, users can work comfortably for extended periods without fatigue.

While it’s worth noting that the device features a five-point energy level scale, including 200mW, which does not seem to function effectively. There are precisely four energy levels: 25 milliwatts (mW), 400 mW, 800 mW, and 1600 mW.
Long-range VTX models with comparable specifications can cost up to $45, similar to those found in high-end drone systems. The unbranded Extremely 1.6W VTX, offering a more affordable alternative at half the price, presents a cost-effective option. Although the amplifier does not accurately deliver its claimed total output of 1.6W, the disparity amounts to a relatively modest 18% discrepancy in theory.
Why not consider purchasing the Ultra1600 VTX on AliExpress?
The General Extremely VTX offers a great value proposition for extended-range FPV pilots on a budget-friendly price range. Designed specifically for larger builds, such as 5-inch and 7-inch quads, this component is optimized for its weight and cooling requirements.
