    Newbie. Hi all from Sydney Australia.

    Welcome! While I live in London I was in Sydney in December (and I was born there a long long time ago, but that's another story) and I really like the CASA rules for RPAs / drones. I flew a few times around Jubilee Park near Rozelle Bay when it was quiet, practising with my Mavic. There are...

    Accurate leveling for IMU / Gimbal Cals

    I bought this especially for the P4 and it is cheap, light and small enough to carry in the same bag compartment as the props. I am sure similar things are available in your region: https://www.amazon.co.uk/dp/B0001P0TNM ("Made in Germany" with 0.5mm/1m accuracy)

    Extreme cards( micro sd) vs other cards

    Only for iOS - the 3.0.0 for Android is (actually) pretty stable ;)

    Extreme cards( micro sd) vs other cards

    They are *almost* OK with the P4 - I make sure they are well clear if I ever do test flights in the garden, but the topcat (Dicky, NOT Leo who is the one in my Avatar) likes to bat at the P4 when it's prop-less and on a table indoors for maintenance :) See about 30 seconds into my first test...

    How do you increase exposure time?

    You can genuinely - or at least I can - take 1:1 macro shots outdoors purely handheld (with enough light). I love the IS on it.

    Extreme cards( micro sd) vs other cards

    8 bits in a byte only works if you use synchronous packets with no delimiters, no start-of and no end-of etc. In a typical streaming protocol it is fair to *approximate* 10 bits to a byte. I speak from some years of exposure to this fun stuff.

    Extreme cards( micro sd) vs other cards

    Also, beware of the headline speed - it is almost always the read speed when what you need to know is the write speed. Technically any Class 10 card or better is enough - the video bit rate is 60Mbps - around 6MBps - but I am using only UHS Class 3 cards - which are rated for 30MBps (~300Mbps)...

    How do you increase exposure time?

    Keep everything. Storage is cheap. DNG (raw) files are the "negatives" and can always be re-processed later with new software or more mature usage as we learn. JPGs are the prints / Polaroids and are only useful for presentation. This debate is about 20 years old, BTW :)

    How do you increase exposure time?

    Thanks, I know what DNG files are. I meant, more clearly, that I normally post-process my CR2 files in Canon's own DPP software - which I find convenient for the level of adjustments I make - and that finding a non-Adobe DNG tool to my liking is still an ongoing process. I am not buying into...

    How do you increase exposure time?

    I shoot Canon and have a decent choice of L glass. It's great stuff, but like all things unless you are in the very top percentile of professionals (which I am NOT) the difference between Nikkor and Canon L is going to be insignificant for the same class of lens (prime, zoom, aperture etc.). My...

    Android DJI Go app update out supporting Mavic

    Please tell us that they haven't broken as much as in the iOS version... I am dreading an update.

    Amateur Insurance in the UK

    I joined What is FPV UK? - FPV UK - they have an umbrella policy that is currently valid until the end of the year and I see no reason it will not be renewed as normal. I ignored the BMFA as they appear, on the surface, to be a bunch of old geezers in sheds who are threatened by quads and other...

    Reduced range in the UK

    I flew my P4 500m up and 1km away a couple of Sundays ago *and* maintained sight of it as a shiny white dot against an azure sky - the sun was at the right angle and the air clear. The new Air Navigation Order only place a line-of-sight limit on UAVs under 7kg - the old rules went out the window...

    Annoyed by people approaching me

    I've only had positive encounters, perhaps because I am positive in turn and happy to talk to people. Some will ask about regulations and I chat about those, pointing out that safety is the primary factor regardless of what the media and amateur lawyers say online. In the UK it's even harder as...

    Flight time & transmission distance TESTED & CONFIRMED

    It's something called the law. There are limits on the power output of certain type of radio device and DJI, like all manufacturers, conform to those regulations/laws.
