Top 5 Best VTX (Video Transmitter) for Mini Quad

Video transmitters (aka VTX) are devices that transmit videos from your drone to your FPV Goggles or ground station. In this edition of “Top 5 Best” we will announce 5 best 5.8Ghz VTX for your mini quad.

The 5.8Ghz video transmitters recommended here are chosen by our group members in a public poll (Facebook group: Multicopter International), as well as consideration on their features. Anyway, please do your research carefully 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.

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

  • VTX remote control (can be controlled from Taranis TX using LUA script)
  • Adjustable output power level down to 25mW
  • Support wide range of input voltage (can be powered directly from battery)
  • Using U.FL connectors rather than standard heavy SMA
  • Small form factor and light weight
  • Support 40 channels or more
  • Pitmode

Matek HV VTX

Main Features

  • Form factor: 36mm x 18mm, exactly half of your FC and cable be mounted on top of your FC stack
  • Support Tramp Telemetry
  • 2S-6S voltage input (7V – 27V)
  • Power switchable: 25mW, 200mW and 500mW
  • IPEX connector
  • 5V 1A BEC (for camera)
  • Nice LED array for power/channel indication
  • Allows wire direct soldering

Very powerful and appealing list of features as we can see above, for only $30!

TBS Unify Pro

TBS Unify Pro - best VTX video transmitter

Main Features

  • SmartAudio V2 – allows you to connect the VTX to your FC, and change VTX settings with your radio TX and OSD
  • Selectable output power between 25mW, 200mW, 500mW and 800mW
  • One of the lightest and smallest for an 800mW video transmitter (5g only)
  • Supports 40 channels, as well as custom frequency
  • PitMode – reduces the power of your VTX to extremely low level while powered up, allowing you to troubleshoot without interfering other racers
  • SMA pigtail is attached with U.FL connector allowing easy replacement

The TBS Unify Pro is a tiny yet powerful VTX. It’s a premium quality product packed with advanced features. One of the most important features would probably be “SmartAudio”. It allows the user to change channels and power using OSD and TX, and it truly brings user experience to the next level. (We have a tutorial coming soon)

If you are not using SmartAudio you can still change VTX settings using the button, and there is a tiny little LED indicating your channel, band and frequency. However, trying to judge your settings by counting how many times that LED blinks has been proven a nightmare.

There are different versions of Unify Pro:

  • V2 ($40) – Output power 25mW to 800mW, but only accepts 5V input strictly
  • HV ($50) – Output power 25mW to 800mW, and accepts 2S-6S LiPo input (up to 25.2V)
  • Race ($30) – Output power 25mW to 200mW, and accepts 2S-6S LiPo input (up to 25.2V)

The Race edition is quite a good deal for $30, if you don’t mind the limited power of 200mW.

Tramp HV VTX by ImmersionRC

Tramp HV by ImmersionrC - - best VTX video transmitter

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 of Unify Pro would be the ImmersionRC Tramp HV. The Tramp VTX is a great alternative to the TBS Unify Pro at only $40.

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).

Eachine VTX03 Super Mini VTX

Main Features

  • Very good value – only $12
  • Tiny and low weights: under 3g
  • Supports 72 channels
  • Power switchable: 0mW, 25mW, 50mW and 200mW
  • Built-in U.FL connector rather than SMA

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 :D but why not?

However one drawback is you can only power the VTX03 with filtered 5V (input voltage 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 circuits.

If you are looking for the cheapest VTX that works, this is the one to get IMO.

Top VTX in the past

Here are some of the top VTX we recommended in the past that are still worth considering today.

Diatone SP3 VTX

  • Stackable on top of FC/PDB for easy mounting
  • Integrated MinimOSD
  • 4 selectable power: 0mW, 25mW, 200mW and 600mW
  • 10V-25V input voltage
  • Supports 48 channels

The Diatone SP3 VTX is a great option as it has OSD integrated (using MWOSD firmware just like MinimOSD). it’s a massive time saver if you know how much trouble it is to install and configure the minimOSD. It’s designed to be stacked on top of the FC, so make sure your frame can house extra height. The selectable power is a new standard in FPV and a most welcome feature.

Aomway 200mW

  • 32 channels
  • Input voltage: 6V-24V
  • 5V output for camera
  • Weights 6g

The Aomway 200mW was voted the best VTX back in March 2016, before all of the VTX above were released. Although it has the annoying dip switches for channels, and it certainly isn’t the cheapest or lightest. It’s a very reliable video transmitter based on user feedback and reviews.

If all you need is a simple and plain device without any of the bells and whistles, then take a look at the Aomway :) However the power is fixed at 200mW on this one so it might not be the best choice for indoor flying.

    Using smartaudio on the unify pro doesn’t break regular audio, you just need to add a small cap and maybe a resistor depending on which mic you use

    input voltage for the aomway 200mw is 6-28v, i don’t think you can even buy the 24v one anymore.

    Rather than the 200mw aomway I’d suggest the switchable version. 2 buttons control power and frequency, with an easy to read led display to tell you the settings. Can select power on or off when battery applied. I run that and the unify pro.

      I’ve always used the Aomway 200 & it has been a very reliable solid option.
      I recently got the switchable 25/200/600 but be aware it is somewhat larger (25 x 30 x 9mm) and maybe a bother to fit in a compact build.
