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!

Drone Dive Paradise!!! (Vortex250 with Runcam Split at awesome location Höllental / Hells Valley)


This is the best spot for drone dives in my region. 30mins drive, 5min walk, 2 massive walls (250 and 300m high), not too far to fly, awesome scenery... I've had some issues first (uncalibrated gimbals on my modded taranis....) but enough time to burn 8 batteries there.
Split worked ok there - still some jello but the ND Filter on it + new props do good. Split is good for my setup here because it reduces weight and increases flighttimes a bit...

If you like this kind of flying - check out my drone dives playlist - I've done a lot (even at this spot, with some major problems...).

Fixedwing dives and cloudsurfing at the same time!

These were some "once in a lifetime" conditions! Not too much winds, enough time and FPV gear working flawless (almost). Had a cloudbase just above the ridge of my favourite wall so I could cloudsurf and mountaindive at the same time. FPV doesnt get much better than this I think!

SJCam SJ7 Star - true 4K! compared with Yi4k and Foxeer Legend 3


Product Link (+TECH Details!):   ►PLEASE SUBSCRIBE
►lots of sample pics

My thoughts / findings:
==================
+ Dimensions match Gopro3/4
+ high buildquality (alu frame)
+- touchscreen nice, but handling not as responsive as smartphone (or Yi4k)
+ touchscreen AND buttons
- charge LED not very visible
- charge with USB MINI (like Gopro3/4) USB micro would be more common?
- scaling down of fast FPS looks terrible
- medium and narrow FOV on 4k makes no sense! should be left out since it produces ugly quality...

Yi4k: lesser distortion, looks "nicer" to the eye - but in 100% crops the image looks less detailed than on the other two cams!
Legend3 has more wideangle than SJ7star, else similar sharpness and details, but "vignetting" on the edges. FL3 has NO! purple fringing!
If you dont have to zoom in (for example film in 4k and then take a 1080p crop) the Yi4k still looks better.
Zooming around in a 4k timelaps on the SJ7star is really nice - lots of details and reserves to zoom...

Batterytime comparison (all 4k 25fps):
Yi4k: 93min
SJ7:  65min
FL3:  53min
