    Hi,
    I've got a 2 axis Radeon on a Cinestar 8, and the tilt stibilasation and tilt have stopped working. The green LED flashes fast then changes to solid when powered up, but as the green turns solid the orange starts flashing fast. Any idea what's wrong?
    Many thanks
    Andrew

    Andrew:
    Is this a configuration that used to work and has now suddenly failed?

    Based on the documentation (see http://freeflysystems.com/pdf/radianManual-v1.pdf) it seems that the Radians are "initializing motor drive." That suggests there might be problem in the wiring getting power to the servos.

    Can you copy the "form" from http://forum.freeflysystems.com/index.php?threads/radian-issue-please-read-this-first.744/ Message #1, paste into a Reply posting and fill in the answers so we can better see how your configuration is set up please?

    Also if you could post some images that show the wiring on the gimbal, especially of the connections on the Radians and the Receiver, that would be helpful -- otherwise it's hard to guess at what the problem might be.

    Andy.

    Andrew: Can you confirm that you're really applying 18 volts to the gimbal please? That's what you say above?
    Are you using some kind of DC/DC converter to lower that voltage for the Radians and the Servos?

    Andy.
