    Hi guys,

    Ive been tuning the gyro on my MK CS8 360 radian kopter, after an hour of playing with the settings this is the best i could do with what i considered strong wings (you can tell by the flags on the video). i didnt tune so much the radians, thats next, but wanted your opinion before keep on going.

    zero post production

    Keep going. Looks like you could use higher gains on both tilt and roll.

    Pretty good for a reasonably windy flight.

    Is there a documented process for tuning mk gains? I am running stock settings now and am getting great results from the go pro footage I have taken so fare with radians.

    What do you recommend?

    the first and final step is to read read read, understand every parameter in the gyro setting and then compare your notes with the kopter behaivour everytime you make a small change to any of the parameters. if you dont understand a parameter, take the kopter up, then down, move the parameter one tiny bit, fly again and you will see and understand the difference, but read up first so you have a global understanding, its a steep learning curve and you may loose a prop or two, but once you get the hang of it its not that hard. here are some links that helped me a lot:

    if your stock setting is flying just fine then you just need minor tuning, dont start from scratch as the documentation says.

    ok i did some further tuning but i still get some twitching, polit says CS8 is flying like a charm. should I focus on the gimbal stab or MK atthis point? i really dont know how much better the stabilization can get

    forgot to put the camera on auto iso thats why its so bright

    Jean two comments. Please share your gain settings. The hardest place not to have some twitching is in a hovering mode. Lots of disturbed air. Take a look at Jeff Scholls videos. We all admire how smooth they are but you very seldom see a hovering shot. Something to consider.

    Yes, camera and gains please. You should be able to get the tilt axis a little smoother but your very close

    With a camera that light you should be able to increase tilt and roll a little more. I run in the 150s with a heavy Canon DSLR setup
