Actioncams compared - Firefly 6s, SJcam M10+, SJ5000+, Xiaomi Yi, Foxeer Legend1, Eken H9, Gopro3+

Over the last months I was looking for 60fps capeable actioncams that are cheap AND good quality. Some guys just buy a Gopro (350$ or more!) and hope nothing bad happens to the expensive cam.
The last addition to my nice collection of cams is the Firefly 6s. Find all the details below!

1. Firefly 6S
2. SJCAM M10+
3. SJCAM SJ5000+

Blade Chroma Review

During my flights with the Chroma I could test most of the functions (hopefully).
Summit: Flight performance great, RTH+follow mode work also great, Wifi Link and cam performance are average. Wifi: 500m are reachable, please check if the cam quality is ok for you - if not consider the Gopro Gimbal version or the CGo3 (4k).

Videoindex Hangar-Review:
01:02 Backpack friendly
01:35 different versions / pricing (this will surly drop!)
03:01 Powering up the Chroma / Radio closeup
04:05 Display on radio
05:08 Flightmodes
06:09 Battery / Flighttimes
07:34 charging adaptor tip: bl8624
09:28 note on follow me / tracking mode setup
10:05 Low battery behaviour
11:29 Video range?
12:39 Props
13:12 motors
13:37 size / weight
14:27 cgo2 video quality?
15:30 final thoughts; Chroma vs. Phantom3...

Videoindex Flighttests:
01:23 takeoff (maiden flight actually!)
02:10 first flight footage
03:02 chasing the girl (and the dog ;-)
03:37 first RTH tests
04:24 first crash on Follow-mode tests (and low-battery landing)
05:44 follow-mode and tracking tests
07:50 Return to home - test (what's home?)
10:13 wifi video link (Quality, issues)
13:34 Low battery behaviour
15:29 updating "Geofence" settings for more than 200m range

Follow or Tracking mode:
you have to enable it ON THE GROUND for it to work; as soon as you're in the air it will follow/track you if you go into smart mode

Test return home:
RTH flies to your current (radio) position and lands around 5m infront of you
RTH flies at about 13km/h and descends pretty fast on landing approach to land very smooth (good autolanding!)

Low Battery behaviour:
vibration alert on radio at 10.6v and the max alt is reduced to 60m - LEDs are blinking RED
initiating autoland (whereever it is at this moment - NOT RTH!)
if you're getting below 10.4vs
I had little over 1min from first alert to autoland.
so if you're out far and you get the first alert - try to fly a safe route home - a route where it can land safely if it chooses to (no water, trees etc.)

28.11.: Flighttime 24min, 500mASL and mostly hovering, did autoland on 10.5v
3.12.: warm battery; 10 degree C sunny, no wind, 700m ASL: 19mins (50% hover 50% flying around medium fast, not much climbing - I was around 50m once)

Range: how to get more than 200m?
As per default the "Geofence" is at 660ft or 200m! And this is a direct line from your Radio to the copter. So height also counts - not only distance as seen from above.
There is a way to enlarge this Geofence:
Download the GUI Software from
GUI Software instructions video

Cam quality below Gopro3, a bit oversharpened, pixelated
Bitrate: 30mbit on 1080p50fps

Nice portability - easy to pack in a sleek backpack landing gear easy detachable cam with quickrelease and only one plug (looks like the wifi happens directly in the cam)
GPS tower foldable

Status leds:
Motor POD LEDs are very bright
RED blinking means LOW Batt! - return imediatly or it will autoland soon where it is!
purple LEDs indicate the "angle" Mode (which I normally flew it in)

well built, all switches labled and logically placed;
gimbal tilt slider on one side, speed slider on the other
Built in touch display with suction cup mounted sunshade - computer is android based
video transmission is 5.8ghz wifi, latency notable (400ms)
- suctioncup mounted sunhood doesnt stick too well (mod it with velcros might be a good idea)
- position of screen is not ideal, screen ABOVE joysticks is better

Props are similar to Phantom - selftightening
10" Props - very silent - efficient
Motor: 3508 780kv. blh8611

Battery: 3cell 6300mah
important TIP: get the bl8624 adaptor to charge on your normal charger to have it recharged faster and with more control over how much juice was put in
25-30mins Flighttime at 0m ASL in warm temps

WEIGHT: 1,3kg
PACKING SIZE: 33x33x9.5cm
gimbal 12x12x8cm
radio: 25x19x11cm
