  • Spring HDMI cable for a field monitor

    I had no idea that connecting a field monitor to a camera can be that hard! Yes, mount or a small head is important, but the biggest problem is a HDMI cable. It turned out that my Panasonic Lumix GH5 mark 2 needs around 30cm long HDMI cable to connect to Feelworld F6 PLUS field…

  • I deleted my YouTube videos. Why?

    I deleted my best-performing YouTube videos. Not here, on my second channel. And when I say they were my best videos I mean it. They were bringing me 30% of new subscribers and 20% of views. Why have I done that? Because I believe, in the longer run, they were harmful to the channel performance.…

  • Caddx Vista is dead – DJI pulls the plug

    The FPV news of the last few days is that Caddx Vista is dead. Or rather, there will be no new manufacturing of Caddx Vista digital VTXes as DJI decided to stop cooperation with Caddx.
