REFLECTOR:Navaid Autopilot

[Jim Agnew]

The oscillation almost always occurs when there is slop in
the control system between the servo and control surface. 
Have someone hold the aileron flush with the wing and move
the servo arm back and forth and look for slop.  It doesn't
take a lot.  If you don't have slop then the sensitivity of
the unit (the dead zone) may have to be turned down.
