Aerial tests and sequence previews for a forthcoming documentary on Farmland Aviation, a private company in Kenya that provides crop spraying services to Northern and Eastern Africa, that will examine day-to-day maintenance of the highly specialised aircraft, the preparation and loading of...

When you make test videos try to stop moving the camera all the time. Let it stay on a given subject for a good 10-15 seconds without moving - unless, of course, you are conducting Pan axis tests. Otherwise it is very difficult to determine whether your mount or airframe setup have any bad...

Much appreciated gentlemen. Yes, I have rechecked all parameters and no, I will not forget to recalibrate the compass before flying.

I am told one can go backwards, i.e. from FWv5.18 to FWv5.16, but a) how to get the older firmware package and b) how to load it? The default firmware process is all geared towards upgrading via an internet connection, rather than from a local file. Anybody know where to get 5.16 and load it?

The word is that those interfering, pansy, busybody, health and safety wee-wee ****s in the EU parliament, Brussels (most boring city in the World) are planning on a total ban of shipping batteries with Lithium content over a certain size. Better start hoarding those 6S packs.

From Kopterworx in Slovenia. Brand name is, 'Gens Ace'.

Forget all about carrying the best part of 3kg in batteries. I use a single 6S 10000 and get 16 minutes with Z15 & GH2. The take-off weight for that lot is already 7.4kg.

Would you take tke 15x4 Gemfans over the 14x8 Graupners? I have read elsewhere your positive comments regarding the Graupners' suitability on the S800.

Good idea. I might give them one more chance. Just have to find a way to reduce the vibes. I have the retract activation set up with logic switching whereby two conditions have to be met before they can operate, Atti/GPS Atti + 360 gimbal mode. I will activate the relay with a similar...

.... if only someone would make them. Always good to have a knowledgeable and objective contribution. The DJI S800 has a bunch of minus points when compared to 'standard' designs - grossly overweight, wobbly booms, expensive proprietary parts - but I have to say that its descending hover...

With the S800 prop length limited to a maximum of 15" about the only thing one can change is pitch. Or is it .... ? I asked APC. This is their response. "At higher altitudes you will need more blade area to offset the effects of the thinner air. Higher pitch will also help but your battery...

My bad. Then does this not lend argument for increasing the prop pitch in order to move more air? If the standard S800 props are somewhere around 15x5 and it behaves well at 100m, I am wondering what sort of pitch increase is needed to cope with 2000-3000 metres. Or perhaps that is not...

Presumably you meant to write lower prop stall speed. Yes, but in order to push more of the thinner air for the same motor effort an increase in pitch is necessary. Finding the happy medium is the trick - assuming one can find a choice of props in the first place. Most things seem to point...

Does anyone know the pitch of the standard DJI S800 15" flat carbon props? Firstly, I would like to change them anyway and secondly, I also want to get some steeper pitched props to cope with higher altitudes, but I would prefer to know the 'starting point' pitch to avoid buying unnecessary...

I find this sort of post really disturbing. There are a whole lot of responsible flyers around who fly within their own and their equipment's abilities and with large helpings of plain old common sense. And then there is the Johnny-Come-Lately FPV crowd who have little or no real experience of...

The Secraft retracts do not appear to be a problem when retracted, i.e. when they are up and the legs are horizontal. It is when they are in the down position that they pick up the vibrations and then shake around a bit, making it worse. The startup issue is intermittent. Most of the time the...

Around 12,000 euros I think. Ouch. Let's see what Boris comes up with.

The firmware update DID load ... eventually ... on a Macbook Pro running OS 10.6 with Parallels 8 and Windos XP Pro. It didn't at first on an iMac running OS 10.5 with Parallels 6. The Sony site lists minimum requirements as Mac OS 10.5, but apparently they are wrong about that. It perhaps...

Thanks for that pokmon. However, I must look for the Mac .dmg version (if it exists) because one thing that aggravates the bloody hell out of me is doing ANYTHING on a Windows PC. Like now, when the firmware update aborted because of WTF, who knows?. Hardly surprising when you consider the...

5D, 7D, nex5n, fs700, cx760, GH2, GH3 ..... its all really the same old, same old with different packaging and a different set of compromises. I want to know more about THIS.
