Would/will buy again
Using this vtx on a 4 inch long range build and it has crystal clear transmission, especially when paired with the caddx ratel camera I'm using it with. The vtx table was easy to setup and the smart audio works without issue.

SOLID BUILD QUALITY. I can't complain about anything.
Great quality, the intergration with Betaflight is very good. Solid signal great on the 3 inch quad on 4S. Minimal footprint for the power it an push. AKK deliverd a SOLID! analog VTX. Fit right at home is a slammed 20x20 stack with a massive ESC. AKK VTX -> HGLRC F7 Mini --> HGLRC Zeus 45A Runnign BlueJay. Solid Combo. Motors are HGLRC Specter 1804-3500KV, GPS HGLRC M100-5883. Frame is rare its a Squirt V2. Camera is a STARDRONE T8-C2. Once you get it all dialed in, great indoor Cinematic build.

Must use low esr capacitor to clean video feed
Great vtx so far works perfect with smartaudio on dys f4 mini fc. I gave it 4 star tho because being powered from 7+ you can't use a 5v pad to power the vtx. Has to be directly from lipo so you have to add a low esr capacitor to get rid of ton of video noise. After you add the cap it's a great vtx

Good as a spare vtx
It works ok, just have a lot of noise when armed. And if I install different vtx to the same quad - there is no noise

Defective and bricked my flight controller
I bought this VTX for my flight stack and made sure all the connections were wired correctly according to the included diagram. When I powered everything on, there were no LEDs, no video signal—nothing. It was completely dead. To make matters worse, the video I originally used as a reference for soldering (which was hosted on Amazon) has since been deleted. This feels suspicious, almost like the seller is trying to hide evidence that they shipped a faulty product. If you’re considering buying this VTX, do yourself a favor and get it from a more reputable seller. I can’t recommend this one based on my experience.

Solid vtx
Replaced a 150mw vtx in my micro with this and as expected get much better range. There isn't much noise filtering so be sure to use a cap. I always run it at 600mw but I guess it's nice to have the other power options for race settings. Smart audio works great

Works perfectly
Ive used this vtx many times and it never fails me and provides a nice clear picture. The mmcx connector is a little weak but there is a backup ufl connector if that breaks.

Waste of Money
