    I'm trying to build a 2dof little model for testing,
    now I have an UNO, a moto monster, 2 mg995(180 degree, not continous rotation one),
    there are the questions:
    do I have to get pots for 1:12 model? how about PSU?
    Is continuous rotation motor nessesary for a motion simulator? or 180 servos can do it too?

    In your interface settings each entry should have the 'a' grouping, like this: <Axis1a>

    In your Axis Assignments the Dir box being checked orange or not determins which way an axis moves. Normally for 2dof one would be checked and one uncheced for roll. Surge is opposite of roll.

    I don't know if this might be the issue but there have been a number of posts about odd movement that turn out to be because of the language setting.
