Great VTX U.FL and MMCX
I had several of these little ones and they work excellent. Clear vision and the range is great too. This vtx has mmcx and ufl so your options for antenna are endless.

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.

Caused me to crash my drone at full speed.
I ordered one and hooked it up, have had a few akk vtx's and they have been great. This one though came defective. Worked well on 25mw but I needed more the other setting above 25mw did not work. It was super static and video cut in and out. Running it on aa speedybee f405AIO45A. I contacted the seller and they replaced it no problem. The second one I received worked great for 2 days after which same issue occured. They arent worth the money. Better to buy a better quality vtx for a couple bucks more

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

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.

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

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

Waste of Money
Don’t waste your money on this there is way better out there at the same price.
