Nov 04, 2010 No Comments by













FEATURES: Ideal for trainers, sport planes and scale aircraft
          Drops in easily in the same mounting space as the O.S. 61FX ABL
          ABL-Advanced Bi-Metallic Liner process uses a double layer of plating
            material rather than one thick layer. This helps the metal bond to
            the cylinder and makes the plating more durable. Also, the plating
            process is more consistent, resulting in a more precise fit between
            piston and sleeve for better compression and longer life.
