The Best VTX (Video Transmitter) for Mini Quad


Video transmitters (VTX) are devices that transmit video from your drone to the FPV Goggles or ground station. Here are some of the best 5.8Ghz VTX for mini quad / racing drones that I recommend.

The 5.8Ghz video transmitters recommended here are chosen based on my experience and consideration on the specs and features. Please make sure to do research before deciding which VTX to get. Here is a guide I wrote a while back you might find helpful: How to choose Video Transmitter for FPV Mini Quad.

I compiled the specifications of all 5.8GHz VTX for mini quad in this spreadsheet so you can compare them more closely.

Common features we see on these top VTX’s are:

  • SmartAudio or Tramp (VTX Control) – you can change VTX settings in Betaflight OSD
  • Adjustable output power down to 25mW
  • Supports wide input voltage, and can be powered directly from battery (4S, or even 6S)
  • Using MMCX connectors rather than the heavier SMA, or fragile U.FL (IPEX)
  • Becoming smaller and lighter
  • Supports at least 40 channels or more
  • Pitmode
  • Solder pads instead of connector

The Eachine TX805 has all the standard features in a modern day VTX:

  • SmartAudio for changing channel and power in Betaflight OSD
  • Built-in Microphone so you can hear the motors from goggles and in DVR
  • You can direct-solder the wires to it instead of using some fiddly connector
  • User-friendly interface
  • MMCX antenna connector
  • It has 30.5×30.5mm mounting holes, so you can install it on top of your FC stack for a clean build

The video transmitter is rated for up to 800mW, however in my testing the maximum power fell short by over 50% at its 800mW level. That’s probably the biggest downside of this VTX, but 200mW and 25mW seem to perform well and accurate. Unless you do long range, 200mW is more than enough for the most part, so that’s not a deal breaker. After all it’s only $14!

The TBS Unify Pro32 HV is a compact yet powerful VTX, it’s regarded as one of the best VTX for a reason: accurate output power levels, clean signal transmission, extremely high quality and reliable.

With an output power of up to 1000mW (or more) in such a small package, it’s extremely flexible! You can use it for long range, racing, or just freestyle, it’s a great option for nearly everything.

Another killer feature of the Unify Pro32 is the support by the TBS Crossfire system (if you are a Crossfire user). You can hook up the VTX to the Crossfire receiver, and you can change channels and power level in Crossfire. This is great for those who don’t run a flight controller, where there is no Betaflight OSD, like a plane or fixed wing.

Either way, you would want to avoid changing VTX settings using the push button, it’s extremely hard to use, and trying to judge your settings by counting how many times an LED blinks is truly a nightmare.

Other Features:

  • Micro USB port for firmware update and configuration (via software TBS Agent)
  • SmartAudio
  • Selectable output power between 25mW, 100mW, 400mW and 1W+
  • The lightest and smallest for a 1000mW video transmitter (8.7g only)
  • PitMode – reduces the power of your VTX to extremely low level while powered up, allowing you to troubleshoot without interfering other racers
  • MMCX antenna connector

The Race edition is quite a good deal for $29, if you don’t mind the limited power of 25-200mW.

Perhaps the second most powerful VTX’s ever tested on my bench – the FX2 and X2 Ultimate by AKK. These video transmitters are capable of 1200mW output power, although they fell short by 100mW-300mW in my testing, it’s still very impressive performance. These are great economy option for long range.

Features:

  • 7V-26V Input voltage
  • 5V 0.5A BEC for FPV Camera
  • SmartAudio
  • Selectable Power level: Pitmode, 25mW, 200mW, 600mW, 1200mW
  • MMCX antenna connector
  • Built-in microphone

Looking for the smallest VTX for your micro quad and Tiny Whoops? There is no better choice than the TBS Unify Pro32 Nano in terms of specs. It’s the smallest video transmitter on the market right now with dimension 15x13x2mm and only weighs 1 gram! And yet it’s capable of producing up to 400mW of output power!

Features:

  • Input Voltage: 3V – 13V (direct power from 2S and 3S!)
  • Selectable output power: Pitmode, 25mW, 100mW, 400mW
  • SmartAudio
  • U.FL antenna connector

Shops: Amazon | GetFPV | RDQ | NewBeeDrone


Can’t afford the Unify Pro32 Nano? Check out the Eachine Nano VTX. It’s nearly as small and light weight as the Pro32 Nano, but at a fraction of the cost. Very similar specs as well, however it only takes 5V as input voltage, so you cannot power it with 2S or 3S LiPo directly, only from a 5V BEC.

Features:

  • Input Voltage: 5V
  • Output power: 25mW, 100mW, 200mW, 400mW
  • IRC Tramp
  • U.FL antenna connector

In my output power testing, the two units that I bought performed pretty well. However there are a few reports of VTX control not working as expected. I guess quality control is probably not on the same level as some other more expensive counterparts.

Shops: http://bit.ly/nano-vtx


Main Features

  • One of the cheapest in the list
  • Switchable power: 25mW, 200mW, 600mW
  • 40 channels
  • Built-in microphone for audio

At only $11, this has to be one of the cheapest but worth having VTX. It’s not the best VTX in terms of quality and performance, but it does work and it’s versatile! I bought a few just for testing FPV cameras, and I even use one on my wing and it works well.

However be aware that this VTX comes with a RP-SMA antenna connector, so make sure you have matching antennas, or get yourself an adapter.

We recommended these VTX in the past, but they are either no longer available, or overtaken by better options above.

ImmersionRC Tramp HV VTX – Top of the Line

Main Features

  • Very light weight and compact (4g without SMA connector)
  • Allows wide range of input voltage directly from LiPo (2S to 6S 22.2V)
  • Supports 48 channels
  • Programmable linear output power control from 1mW to 600mW
  • OEM Integration (similar to SmartAudio)
  • PitMode
  • Supports TNR wand (touch and race), a remote that configures your VTX settings without touching the transmitter (purchase separately)
  • Resilient against voltage spikes
  • SMA pigtail is connected with U.FL connector

Another high end VTX that can match the features on the Unify Pro would be the ImmersionRC Tramp HV. The Tramp VTX is a great alternative and it’s $10 cheaper than the TBS Unify Pro HV.

You can change channel and power with your Taranis via LUA script too on the Tramp. (tutorial coming soon) However on the Unify Pro, you will lose audio capability. On the Tramp, you can still have audio because it doesn’t occupy the audio pin, because it has a dedicated telemetry port for this purpose.

The TNR wand is a great accessory that makes the Tramp more convenient to use. You can change VTX channel, frequency and power without touching the transmitter at all (if you don’t use the Taranis / LUA script hack this is a good solution).

Holybro Atlatl HV V2 VTX

Main features:

  • Stackable on top of FC/PDB
  • SmartAudio VTX Control
  • 4 selectable power: 25mW, 200mW, 500mW, 800mW
  • Supports Pitmode
  • 7V-28V input voltage
  • Supports 48 channels
  • Built-in Mic
  • MMCX Antenna Connector

This is a very versatile option with nearly all the features one would want in a VTX. It’s designed to be stacked on top of the FC for easy mounting, but make sure your frame has the extra room for that. Maximum output power has been increased to 800mW from the previous version, which allows you to go further in range.

Oscar’s Backpack VTX – Budget Smallest

Main features:

  • Tiny and light weight: 2.8g
  • It can be mounted on the back of a micro FPV camera!
  • Power switchable: 25mW and 200mW
  • MMCX connector
  • VTX Control using SmartAudio telemetry protocol

The OBVTX is a tiny VTX, yet it packs with unique features that were previously missing in existing products. It’s compact and you can also mount it directly on the back of your micro FPV camera. It’s got SmartAudio, as well as a push button to change settings. It has a maximum power up to 200mW, and supports 25mW and pitmode.

It has a MMCX connector so you don’t have to worry about breaking the fragile U.FL anymore. If all you need is a simple and plain device then take a look at the OBVTX 🙂

Runcam TX200U VTX

It can be stacked on the back of a micro FPV camera such as the Micro Swift 2. This makes mounting the VTX super easy especially for a tight and light weight racing drone.

The TX200U comes in “Lock Mode” which limits the power output and channels you can choose to follow regulations in many countries related to FPV. However you can unlock it easily if you wish and I think that’s a great safety feature.

Downsides are you can only power it with filtered 5V (3.5V-5.5V), that’s probably the reason why it’s so tiny and light because it doesn’t have voltage regulator and filtering.

Eachine VTX03 Super Mini VTX

The Eachine VTX03 is a super small, light weight and affordable VTX. It offers decent performance as far as we can see from the video reviews online. It comes with U.FL connector just like the Unify Pro. If you prefer to use antennas with SMA connectors, you can add a SMA pigtail with U.FL connector. The 72 channels support is probably an overkill for most of us 😀 but why not?

You can only power the VTX03 with filtered 5V (input voltage 3.5V-5.5V).
