    Maybe because we dit a research and testing for about a half year to find the right combination, copycats just copy and trow it on the market without research and testing to make max profit without labor cost ;)

    Look at the picture and you see that that is no option because we designed it around our own frame.

    Pavlos first all of the standard questions. Props balanced, aligned, camera balanced on the gimbal without the belts, overall copter COG checked in MKTools? Then the gains you are using.

    A suggestion in general. Unless you show a steady shot for about 10 seconds, i.e. not tilting panning going on, it's a bit hard to analyze the video since there are all of the other movements happening.

    Mario looking forward to seeing some video with the wiredampers from the Sony with BOSS turned off since with it turned on it would mask some of the vibration and a lot of folks don't have image stabilization on their lens that they fly.

    Deal Gary, but not maiden it yet so it will take some time.

    This was a shoot with the hexa with wiredampers, camera GH2 on PH-AV130 with the picloc Pro, for sure the CS3 with the Radian's will better this.

    Mario, that is one sexy beast!
    Do you plan to make it available for sale in the US? What's the price for the frame? And are you using MK electronics? And what camera gimbal?

    Looks like a ZeroUAV GPS on the top... guessing they are going with the Y6 FC from them.

    Thanks Steve:)

    Like josh said, this one is using the YS-X6 FC but the frame also support standard DJI and MK FC's, no MK ESC's though, they are to weak for this kind of power (33,6Kg total lift), mount is the CS3/Radian3, it's designed for lifting RED Epic camera's.

    It depends on many factors such as mass of the camera, balancing, etc. If we are still talking about the CX760, Id start at the defaults and move up if you see any kind of lag in the movement. With the BOSS stabilization you'll find a wide range of gains are possible. Tuning cameras without stabilization is will take a little more fine tuning.

    Ok default it is, but pan is on default and slowly drifting when I hang the copter with rope's on the sealing, is this normal or must I raise the gain?

    The Radians calibrate for the first 2 or 3 seconds on power up. During this time they have to be stable. If you hang the gimbal and then power up the Radians you will get movement. So.. Yes.. this is normal if you powered up the Radians while they werent perfectly still. Power up on the table/floor and then hang the gimbal.

    Maiden of the Kratos, Radian's are looking good, roll need some tuning though.
    YS-X6 and radian's all on default so nothing is tuned yet.

    Mario, this is Josh Kornoff from Allied Drones. We have never met, so I am surprised and highly offended that you would say something like this about another organization. Why would you say something like this?

    1. The Live Wire mount works/worked very well. We no longer manufacture it for a multitude of reasons, none of which have anything to finding the "right combination" as you say. This couldn't be further from the truth.

    2. We do not "copy" other peoples designs, thank you. The basic wire rope isolator has been around for a very long time here in Hollywood and can be found on practically any good hothead camera mount I have used for the past 15 years. This concept is nothing new. I apologize directly to you if you are the original inventor of this great style of isolator! They work great!

    In the future, I hope you would be less quick to offer your insight into other peoples business and concentrate instead on improving your own work.
