$250. Sigma-Tek Directional Gyro (DG) - Autopilot Input - 14V Model 4000 C-1 Century Part # 52D54M Removed from my A36 when I had my new G3X system installed. Working great when removed. Seller pays shipping cost - you choose method. Item can also be picked up at Fullerton Airport (Southern California), or I'll meet you at any airport within 100 miles of KFUL. I'll take any excuse I can get to fly!
