Appears to be an issue with the electric over hydraulic aerial controls. Left and right controls have a long uptake and an abrupt transition into motion. Left and right control function do not have slow throttled speed. Checked manual control. Those are ok. Will need to verify ramp voltage setting for right and left functions. Excessive backlash on pinion to ring gear to contributing to “jerky” side to side movement. Attempted to adjust backlash and turned the pinion to adjust and retested. Found now bottoming out in the gears which will cause more wear. Emailed Hughes and they recommended a pinion and ring replacement as the pinion and ring gears are worn. May need further diag. But current issue will cause excessive abruptness for left and right especially in windy conditions. Undiagnosed engine misfire, possible failed exhaust cam lobe for cylinder 5.
