    Hey Fellas... I have the 3 axis upgrade kit from Qudrocopter. It comes with some electronics, but as you probably know, not everything you need to be operational. I'd like to find out what combo of electronics you guys like and what all I need to be up and running. I know the new kick awesome gyros are coming soon from Tabb, but for now I'll be running the flight control board.
    What I have now:
    MK 2.1 Flight Control Board
    Graupner MX12 Trans/ GR12 Receiver
    1200 Lipo

    As I said in the title, I'm a newb, but learning fast. If you guys could consider a brief write up with some killer pictures I would appreciate it greatly and buy you a teddy bear.

    I believe you have all you need. You will need to do the firmware update for gimbal FC boards - the video and file available on Vimeo.

    Email me direct if I can help by walking you through it.

    I've also upgraded the firmware to the 88f "Walter" version an got it more or less running. I find that the servo compensation in nick and roll affects both the reaction time of the stabilization servos and also the degree of under/over correction -- so I'm having to tweak that.

    I also find that the yaw motion is hard to set up to get an ease-in/ease-out.

    I'm using a Dx6i to control the MK FC board so I'm tweaking the rates/expos. You have to avoid tweaking the rate for the Yaw too much otherwise even full scale deflection of the stick will not allow calibration of the ACC and gyros.

    Email me at if you have specific questions. We've got the makings of a support group here, I think. :)
