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.

Newly designed 61D carburetor with a rearward angled needle valve for safer adjustments

Two year limited warranty through Hobby Services beginning at date of purchase
