Is it possible to build an steam gauge type attitude indicator , using the 4 servo phidget. I have set up the pitch and roll ofsets to drive their respective axis. Each axis is being read correctly, but the servos only drive from stop to stop. I can also see the values of pitch and roll change in the (fs value ) field. The direction of servo travel also seems correct. The direction only changes when the aircraft pitches or rolls through 0 degrees. Help ANY one !!!!!
