Digital HD video downlink! (Interview with FPV Blue, long range low latency)

We're waiting for some serious HD video transmission now for a few years. Connex prosight was promising and is still the most used? - ok Lightbridge and Occusync from DJI are market leader - but they have very high latency...
For "real" FPV usage we need lower latency, reliability, range. All being promised by a small, dedicated company - FPV.Blue.

Join me in the hangar for a closer look at this new system, check out the menu options, see the latency measured, and see me interviewing Davide from FPV.Blue.

!DISCLAIMER! - FPV.Blue sent me this product for review, you can buy it here

Groundstation Recordings (a bit troublesome to work with as of 16.Oct.2017 - should be improved with next firmware):
can be played back with MPLAYER  
there's also a GUI version (SMPLAYER)
Recordings do not get corrupt when power is lost

Runcam Split 2 - firstlook

Runcam sent me the NEW version of their popular SPLIT cam. They changed some bad things to the better!
- New SD Card mount - yay!
- larger VOLTAGE RANGE (5-17v)
- FC integration!
- Lens
- WIFI stick instead of board with 90° angle it's now a horizontal one

I will make a more indepth video for sure - but this will take a few days or weeks. Give me feedback on what you want to be tested!
