Review: 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.

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.

### ⭐ Caused me to crash my drone at full speed.
*by P***O on August 2, 2025*

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
