    From the Radian FAQ:
    How do I limit the angle on tilt, so I do not see the booms?
    The Radian comes set with a 10º up angle limit and a -110º down angle limit on tilt axis. Roll axis comes with a +-30º roll axis limit. Please note that these limits are with respect to the Earth, not the multi-rotor airframe.

    So the short answer is no you cannot limit the end point by software -- but, knowing that the Radian sensor will not tilt up more than 10 degrees from horizontal, if you're trying to prevent excessive tilt up (to avoid a boom in shot), you can do this:

    1. Power the system off.
    2. Loosen the camera plate just to the point where you can rotate it about the front transverse boom on which it is mounted.
    3. Rotate the big pulley (and, of course the servo pulley) so that the Radian sensor is approximately 10 degrees above the horizontal.
    4. Now rotate the camera plate to the maximum tilt up you want and tighten it down on the boom.

    That, in effect, limits the tilt up.

    Hope this helps.
