AKK FX2 5.8Ghz 40CH 25mW/200mW/500mW/800mW VTX

There are many FPF VTX systems on the market these days and AKK keeps making new products almost every two weeks. This time, I have tested their new FX2 40CH switchable VTX.

So let's start with specifications first:

Output power: 25mW, 200mW, 500mW and 800mW power switchable
One button frequency and power setup
OSD configuration using FC Uart
7-24V input with 5V output
Integrated MIC
All up weight: 13.82 g
Dimensions: 30.5*30.5 mm

As all new AKK video transmitters lately, this one also has Smart Audio port which allows you to change channel band and frequency and even power output via your BetaFlight OSD controller. PitStop mode is also present (that mode transmits with very low power output ,around 0.1mW, and if you accidentally enter channel that someone is using at that moment on the race track, he won't loose his picture because of that very low output). Antenna connector is MMCX and in the package there is MMCX to SMA cable, so you can use your existing antennas with this VTX and place it anywhere you find appropriate on your drone, plane...

Setting up band, channels and power output is very easy with one button, and is described in video below.



Time to test picture quality and range. As always, I am using Eachine EV800D googles (Link on Banggood) with standard antennas, so nothing special and pricey.

It was -1 °C that day in Croatia, with very cold wind...I was thinking of making range test, but at 2.5 km range, my fingers froze, and I had to return back. Anyway, at that range I had no issues with picture as you can see in video footage. Perfectly clean picture. Nice job AKK.
