Matek VTX-1G3, VRX-1G3 and ANT-Y1200 ready for testing

The upcoming 1.2GHz FPV system from Matek called 1G3, where VTX-1G3 is the transmitter and VRX-1G3 is the transmitter and ANT-Y1200 is the antenna, are ready for some flights!

So far I have a couple of remarks:

  1. VRX-1G3 fits nicely inside a standard Far Shark receiver bay and you can use the standard bay cover too. SMA connector is in the correct place! The standard cover blocks access to the button that is used to change channels. You can not change channels from the goggles menu.
  2. ANT-Y1200 has a nice stiff coax cable and you can position it however you want
  3. ANT-Y1200 is much bigger than antennas used for 5.8GHz FPV and it's much harder to find a good place to position it on a model.
  4. VTX-1G3 is luckily small enough to fit in many places and does not overheat. Even when powered from 4S it stays relative cold (50C) at 28dBm of output power. I got the word it's because of much more efficient energy conversion that is possible with 1.2GHz band

Matek 1G3 VTX and VRX – Long Range 1.2GHz FPV video link that fits your goggles!

There a few things that I can be sure of in life. One of them is that every time I receive a DHL package from Matek, there is something very interesting inside!

This time, for example, is a pre-production sample of a new FPV transmitter and receiver. This time it's not 5.8GHz but 1.2GHz. Long Range FPV, here I come!

Probably the best feature of Matek 1G3 receiver is that it is Fat Shark receiver module compatible! You can just plug it into your FPV goggles or a ground station receiver like Furious FPV Dock-King!

It comes with Matek made 1.2GHz PCB antennas as well!

Realacc UXII circular polarized 5.8GHz FPV antenna – Lumenier AXII chinesium clone

Cloners gonna clone and chinesium keeps being chinesium! It did not take long for Banggood / Realacc to clone Lumenier AXII FPV antennas and call them Realacc UXII circular polarized FPV antenna. Coincidence? I do not think so.

I've ordered few of those in December, they arrived last week and this is what came in package

Unfortunately, in this case, the build quality was typical chinesium. As soon as I opened one of them, antenna disintegrated… oh bugger…

I only hope the other (the one I did not open) works like expected. I did not test them in real life conditions since the weather is rather bad over here. This weekend maybe… In a meantime, here is a video of what is happening inside Realacc UXII 5.8GHz antenna.

Hands on: Matek 5.8GHz 40CH VTX-HV in an interesting form factor

Is it only me, or is Matek starting to build very good FPV hardware? I think everybody knows Matek's PDB. Matek F405 flight controller series is also very popular. But do you know Matek also started to build VTXes? I didn't and when a friend showed me this:

Matek VTX-HV 5.8GHz 40CH 25mW/200mW/500mW

I almost knew I want one. Matek 5.8GHz 40CH VTX-HV is quite interesting design. It can be mounted above flight controller: M3 mounting holes are 30.5 apart. That's not all, it supports serial protocol (Tramp), can be powered from 5V rail or main LiPo (7-24V), has u.fl IPX connector, comes with small dipole antenna and SMA pigtail, has 3 power levels (25mW, 200mW and 500mW) and supports Raceband.

But the best feature are: 2 buttons and a set of LEDs. It really makes setup super easy. Press Button A to select function, press Button B to cycle options (power, band, channel). And current state is presented with LEDs. Cool. Not like with TBS Unify Pro where you have to count blinks!

Errata

Bangood stated it uses SmartAudio, but it is not true. It is ImmersionRC Tramp protocol. Thank you Andrey for pointing that out.

How FPV looked 2.5 years ago…

A few days ago I went back in time. Or to be more precise I started to browse my photo archive. And I've found pictures of my first FPV quadcopter… Oh my… ancient times…

my first FPV setup with OpenPilot

Doesn't it look awkward? At least a little… But this baby was pretty cool to think about it. At least when I finally learned how not to crash every few minutes. If I remember correctly, the specification was more less like this:

  • Flight controller: CC3D running OpenPilot!
  • Afro ESC 20A with BLHeli
  • Turnigy MT2213 935KV motors
  • 10" APC props
  • FlySky/Tunigy FS-i6 radio link
  • Some cheap FPV set I've found on HobbyKing with VTX, camera and crappy bucket goggles

History… and what was your first FPV setup?

Video tutorial: 5.8GHz Inverted Vee antenna for FPV

Today another video tutorial. It's just simpler to show how to make something on video than with text and images. So, without further ado: How to make Inverted Vee antenna for 5.8GHz FPV at home. All that is required is:

  • coax cable (here RG316)
  • SMA/RP-SMA connector
  • copper welding wire
  • caliper
  • soldering station
  • basic tools

At the end we have small and light FPV antenna that just works. Sometimes it's just worth to make something by yourself, right?
