    4K, the future standard

    Unless you are regularly working in the film industry I cant see any need for using a Red especially unless you have perfect stability in the gimbal which is not possible with the .5 degree limit on brushless rez. (So wide angle shooting only). The new Sony 4K camcorder with image stab built in...

    Congrats to Tahoe Ed!

    Brushless Motors v. Voice Coil Actuators

    Speed is very much faster. Accuracy is considerably better. Power is also much better as it can run at full battery output and not even get warm. I have reloaded the video at https://vimeo.com/85620396 as I was getting DDoS errors. What this quick video is showing is that a standard SBGC can...

    Brushless Motors v. Voice Coil Actuators

    Actually it is no contest because even with the upcoming new generation of motors they will not cut the mustard against the motion control de rigueur solution for mil spec. gimbal control. The VCA comes in many different forms and you will find them inside of camera lenses and even Hard Drives...

    This ones for our Russian,Greek and Arabic speaking friends

    Some of the older mothers were still idolizing him. Does the name Arkaidi Sharov mean anything in Russia. He was the man who put up the money. They say he made his money in marketing!!!

    Endurance

    Nice one ferdinand We now pass 2 hrs and start a new challenge for the future. What are those batteries? are they the same technology as the Panasonic ones. I ordered a set of Panasonic ones from Germany six weeks ago are they never arrived so my attempt with a tricopter is stalled at the moment.

    This ones for our Russian,Greek and Arabic speaking friends

    When the Russians in Limassol throw a party they do it in style. An empty car park on the seafront and a couple of million euros and you get 30 days of xmass entertainment. Shot with a standard Phantom Vision-2 plus a stage GoPro and a 5D/85/1.2 for the main stage also a iphone 4S:tennis:

    Need a small high quality point and shoot with GPS tagging

    Yes EMO it is a very simple but effective solution. The lens is 60 deg.

    Need a small high quality point and shoot with GPS tagging

    There seems to be an awful lot that you don't understand, The GoPro does not have any focussing system, it is set and fixed. If it is not sharp then refocus it. The metering is excellent. Because the size of the sensor is what dictates the size and weight of everything that you will eventually...

    Multi-rotor used on Gold Rush,

    Perhaps we should give DJI a little credit for making it all possible.

    It is an admission that they have a problem which is not in keeping with the usual policy unless they have a solution at hand.......

    foxtech supreme carbon fiber prop test

    Yeah the much cheaper 17x5 high aspect ratio prop. may be better. I have them both on the test rig at the moment.

    Phantom motor/ prop. efficiency

    I had a Hacker A20-22L evo. kicking around and I though that this quality product was worth a test. It is very nicely made with good bearings and curved powerful magnets but that 3 mm shaft that needs a prop driver extends the prop. too far from the top bearing and it went through some...

    Phantom motor/ prop. efficiency

    Whilst waiting for some decent weather to come my way I have been running the test rig on a few motors ESC's and prop's. Without going into a lot of data that nobody really cares about anyway. Here is my results based on a Phantom operation. On the sampled standard motor I was please to see that...

    Motor stops twice in mid air on hexa

    Your problem is definitely an ESC mismatch. Some of those tiger motors need a lot of advance to stop them loosing phase sync. That is not the root cause of your problem but a way to cure it so it runs ok. What you need to be able to do is snap the throttle open a few times from idle. If it...

    colin guinn booted from DJI

    Colin Guinn seemed to be around in the very early days of DJI when they were more centered around SR heli dev. I think his contribution to the hobby has been good as he was no stranger in front of the camera and his videos were great for the newcomers to the hobby. I think his snorting side kick...

    colin guinn booted from DJI

    Well Guys I just heard it from the top. This is not a rumor it is true. Lets not get into any personal stuff about Colin as I'm sure it will all come out in the fullness of time. But he is no longer with DJI NA.
