Eachine TX805 5.8GHz 800mW video transmitter hands on
I have something like a personal problem with “the best FPV transmitter manufacturer”. It’s about ideology.

FrSky R9M and R9 Slim long range radio system review
When FrSky R9M long range transmitter and FrSky R9 receiver series started to pop up some time ago, there was a lot of speculations “it is any good?” “is it a Team Black Sheep Crossfire killer” “cheap Crossfire alternative?”. In time, new firmware started to appear, new receivers and so on. And oh yes, EU…

Team BlackSheep tries to start a war against FrSky due to new FrSky antennas or what?
