AKK AKK A1819(US Version) 5.8G Long Range VTX 200mW/400mW/800mW/1000mW Switchable Transmitter Support Smart Audio

Excellent range. Does get super hot though. But to be expected.

Great VTX for the price. But be careful - this thing gets hot, but the heat sink seems to do it's job. I have forgotten to turn down the wattage on the bench and although it got super hot, it still was pushing the signal out. Just don't grab it in the wrong place. You will get burned. Only drawbacks for me are: 1. the antenna plug and the cable to the flight controller are on the same side. this means in a quadcopter, you will have to decide weather you want to route the antenna back over/under the vtx or turn it around and route the signal cable over/under vtx assuming you want the antenna in the back of the quad like most models. Both scenarios are not ideal and can cause some minor level of interference. 2. There is no pit mode like other similar VTXs. On this one, since it gets so hot, it would be very, very useful. I wrote to AKK and asked them if it was capable of pit mode and they just replied, "OK" which made no sense but it's a funny story, so maybe worth it. I don't think they speak good English, but at least they replied to my email. Like I said before, though, it's a great vtx for the price. I liked it enough to buy a second one for another quad. Also, thank you, AKK for not having a nonsense, weirdo brand name like "DreamGoo" or "EveryEndingRC". We see you and appreciate you.

Works as expected. Tested with Caddx Infra 2 cam, no complaints. Extra TX power feels great. Gets hot when on max power, make sure to give it room for some air. LEDs are not marked, kinda confusing. English manual is unreadable, as usual.

This thing goes up to 1600mw! I’m pretty sure it’s the most powerful 5.8 vtx on the market currently. It’s great and really robust. Anyone saying they are bad is user error guaranteed. Sure I’ve roasted a couple of these but was 100% due to user error. Otherwise they last forever and get huge range!

Not my favorite VTX, yet is a functioning VTX for backups. Would need 30x30 holes to mount the VTX. VTX has soldering pads to connect to FC via wires instead of wires and connectors. I love this feature. Here is the rub, the audio quality is not that well. There is less volume when watching the recorded videos in contrast to other models, like HGLRC and Rush FPV. This one has the lowest volume, more noise than the actual motors. I fly analog just for the fact the VTX will broadcast video and audio. It would had been very wonderful if there were extra pads to solder a microphone on them.
