FX3 5.8Ghz 25mW/200mW/400mW/600mW Switchable FPV VTX with MMCX Integrated OSD FC Configuring via Betaflight Flight Control Board

After frying my Speedybee VTX I figured I'd try this one. It has been working perfect for me so far. It connects to Betaflight with no problem and the OSD appears as it should.

The media could not be loaded. video was recorded at 600 milliwatts on my phone with an analog to digital receiver so the static is greatly exaggerated. I never did get smart audio or the built-in OSD working but I did make a mistake failing to route the video through my f3 Magnum flight controller that had its own integrated OSD that I originally thought was integrated into the original VTX that the stack came with which is fine because all I really wanted was the crosshairs and low battery warning to land anyway. If you're trying to make smart audio work on a f3 Magnum FC it's not going to work because the most recent firmware for Omnibus is older than the necessary 4.1 required for smart audio compatibility.As for overheating the VTX that tends to happen when the ambient temperature is above about 90° if you allow enough cool down time between flights, keep it in the shade and get it flying quickly after powering on so you can get air flow over it it'll be fine. If you start getting watery and technicolored distortions in the video feed it's probably overheating so power it off immediately and cool it down! That's happened to me a couple times now and it's still working fine.Outstanding VTX by AKK well done!

transmitter gets very hot, does not work above 25mw, and just about fried my fpv plane's receiver. Would return it, but had to cut connectors for it to work with my camera to even test it. Gave two stars because it does technically work, but there are better options out thereOne week later, updating review: turns out it wants much more than 5v so that is my bad. Put it straight into the 11v 3c battery, instead of the receiver. It does transmit at the full 600mw now, but even with higher voltage it gets pretty hot, and with no sort of heatsink, makes me think it isn't long for this earth.

Don’t bother getting this just get a Zeus nano vtx

I have a couple of these. I have heard these may bleed over-frequencies and power output tends to be higher or lower than stated. These are only a problem if you race or fly with large groups.My experience is these are great!!! I get crystal clear video OSD control for frequency and channels and the MMCX connector is great. Coupe this with an AXII 2 antenna And a 90 degree MMCX to SMA cable and you get a compact durable high performance stack. I am buying my third, And yes i am buying another not replacing a broken one LOL!

Great little VTX if you need a 20x20 stack build but I will warn that it did bleed onto a few channels and pumps well over the advertised power output. If your FPV racing it may not be the best because of that but if you fly freestyle by yourself then it's perfect. Excellent range and clear video. I love the plug connections and the MMCX connection.

This little VTX is absolutely amazing! It was extremely easy to install and the Smart Audio works perfectly! It has pit mode, so you can power up your quad without blasting everyone else out of the sky. The range was incredible, providing crystal clear video, both indoors and outdoors,even around trees and small buildings. I can't believe this was only $18.99. Everyone with a 20mm board needs to get this VTX. Highly recommended!!! I can't wait to try the full size version on my 5" build.

This vtx its great I used for my 5 inch drone its not to big its the right sizes and works great. This is one of my favorite brands.
