Began to rig the anti-servo tab. Once the wires and turnbuckle were in place, I noticed the nose gear was not completely centered. Looking at the directions for the SH3, it was not sure the moly grease was applied so I disassembled the nose gear control. I discovered one brass sleeve was out of round and did not rotate freely. I filed it and polished the brass sleeves and reassembled the nose gear steering.
