DJI Inspire1 indepth Review (App, Firmware, Frequ., Flightlog, german voice / english SUBTITLES!)

►Videoindex / Highlights:
10:27 - Transportmode - Startmode
14:00 - App genau angesehen
21:08 - Cam Steuerung mit Finger auf Touchscreen
23:50 - Flugverbotszonen
26:34 - HDMI Kabel für Dominator HD
27:18 - HDMI OSD Anzeige auf Monitor
28:07 - Latenzmessungen
29:07 - Fazit
31:34 - Firmware Update
34:48 - Naza Danze (Kompass kalibrieren)
36:13 - Frequenz Analyse (2,4 und 5,8GHz)
40:05 - Flightlog - Excel - Nerd Heaven

►Flugzeiten: im Durchschnitt 13min bei 3500mah Verbrauch beim 4500mah 6S Akku
Flighttime around 13min avg with 3500mah usage out of the 4500mah 6S battery

►Max Speed 80km/h

►Weight/Gewicht mit Akku (4500ma): 2936gr

►Preis: 3200€ mit einer Fernbedienung
(z.B. bei
Pricetag 3200€ with single remote

►Reichweite? / Range?
Bodentest noch ausständig
1-2km geht sicher, Videolink sehr stabil
In der App per Slider zwischen guter Videoqualität und niedriger Reichweite (10mbit und 700m) und geringer Quali aber hohe Reichweite (4MBit und 3km) wählbar

1-2km no problem - some users get really far (like 6km) which is dangerouse with limited battery time! You can adjust the image quality (vide bitrate) and get better range - app tells 3km Range with lowest quality (which is still really good compared to all other video transmission I've seen so far!

►Zeitverzögerung beim Video:
Echtzeit - App-Bildschirm: 250ms
Echtzeit - HDMI Bild nur 80ms? (zumindest ist HDMI und App ca. 170ms auseinander)
(hier aber leider nicht besonders genaue Stoppuhr und Messung)
Jedenfalls im normalen Betrieb nicht störend, beim fliegen nahe an Objekten evtl. etwas ungewohnt - Vorsicht!

Lag: looks like Lightbridge to HDMI is quite fast (only 80ms? not really sure about my measurements) add some 170ms more if you use the app (measured the Android app on GalaxyS3)

Resolution 12.0MP
FOV (Field of View) 94°
CMOS Sony EXMOR 1/2.3”
Lens f/2.8 (20mm equivalent)
Burst shooting (BURST: 3/5/7 frames,AEB: 3 or 5 bracketed frames at 0.7EV Bias)
Time lapse
HD Video Recording Modes
UHD (4K):4096x2160p24/25,3840x2160p24/25/30
HD: 1280x720p24/25/30/48/50/60
Max Bitrate of Video Storage 60Mbps

►Transportkoffer aus Kunststoff, 556 × 490 × 240 mm

►Dominator HD HDMI Kabel
und dieser Adapter
Oder ihr findet ein Kabel:
MINI Hdmi auf Micro HDMI (ich fand keines)

auf Android: "SmartPhone"\Phone\DJI\dji.pilot\FlightRecord
auf iOS: über iTunes auf die DJI Pilot App und hier die Dateien runterladen
die Files dann hier hochladen:
dann erhält man lesbare Files wie im Video (ganz am Ende) beschrieben!

You get a really impressive ammount of in flight data in the flightlog. Get it from android from \phone\DJI\DJI Pilot\FlightRecord
or from iOS using iTunes and seach for data on this app.
Convert it using the link above and you get a KML file for google earth with the track and CSV files (for excel) with many parameters.

Jet Crash, Lipo Barbecue and Mini Racing

Had some great fun with my miniquad yesterday on the field. And there was some action (another crash, some burning lipo, rescue flight, a few stunts,...).
Please be careful when you handle your lipos. You see in this example how much energy they have and how explosive/flameable they are! Always be safe while charging those lipos also!!!!

MiniQuad exploring abandoned Soccerfield "Lindenstadion" in Eisenstadt

Once again I had my mini with me on a small trip to the nice city in Burgenland called "Eisenstadt" (Iron-City). They have a nice Esterhazy Castle and very beautiful park behind it - open to the public. While walking through this park I looked for a nice spot to fly - and finally we came to that ugly brickwall. I was curious what's behind and found a soccerfield there (didn't recognize it as such in the first place).
It had been abandoned after the soccer club went bancrupt a few years ago. See a few pics from older times at the end of the video...

The flying there was really exciting! Naturally the stairway with a passage under it was like a magnet - and I was not sure how the video and control link will hold up. See if it worked or if I had to do the walk of shame ;-)
