Product Details
Key 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
- O.S. 65AX ABL, 61D carburetor, E4010A Muffler, #8 Glow Plug, Needle Extension Cable and Instruction Manual with Decals
