Cambrian Rally Press Day 2013

Here is the footage of the Cambrian Rally press day.  The conditions were a bit challenging as it was blowing a good 20 +  mph. Remember to watch it in HD

Another stunning video Zaid, nice one.

Thanks Mel, working towards hanging my fins up !!

Great vid that zaidy I can see a successful business and also an exciting one starting up soon  

Very good Zaid  

I like the panning you're doing. A thought - could you program in some waypoints so that you follow the road from the side? Then of course you would be able to follow a vehicle over a much greater distance

Thank guys

@Allan, yes you could, but we could just about keep on station so even if we had the way point programmed we would not have been ale to keep up especially when some of these boys doing 100mph in some places !!

Love it Zaid, just a quick question did you start at road level where the cars come past or where your car is parked, reason is, would the flight controller sense that the hex is lower than the start point if you started at a higher level than you were hovering at.

Great question that Rich, I didn't knotice any issue with mine below the slope when I tryed it though

Hi Rich

Thanks for that.
Started at road level where the cars went past.
Interesting question though. I cant see it being an issue ! but I could be wrong.

Where's Andy when you want a lecture?

If I am not mistaken, the NAZA uses GPS and barometric pressure for Altitude so the unit know where it is in space !!

ANDY ???

I can read too

Thank God for that I was beginning to wonder!!

I would have just posted the link to the manual

Nice vid Zaid.

The main altitude control on the Naza is via a barometric pressure sensor. GPS is a bit shite when it comes to altitude control, not unusable, but typically has an accuracy of around 10-15 meters or so in the UK. A pressure sensor can usually read altitude to within 10-15cm over around 10 minutes (disregarding dynamic pressure effects).

The flight controller is not really bothered where you are in terms of altitude, unless you invoke the RTH failsafe (where it climbs to +20m from the home point, before coming home). In normal flight, it only ever uses a relative altitude to hold its current altitude. I.e. it doesnt care where it is, so long as it doesnt change, much. It would be quite easy for DJI to mod the software to include a lower flight limit though, and not let it fly below a certain level. The V2 Nazas and wookong already have a radius and altitude limit in the software....

Cheers Andy,

Just what you said Zaidy in 23 words
