Overview

The power source for 60-sized aircraft.

Power up your big bird the easy way: simply swap out your 61FX with the awesome 75AX ABL! It uses the same mount and fits the exact same bolt pattern, so there’s no modifications required. The angular head not only looks sharp, it also significantly increases surface area for better cooling. A diagonally positioned needle eliminates the need for a remote needle valve. Plus, you get a Power Box muffler that’s small in size, but robust in volume.
  • Fits the same mount and bolt pattern as the 61FX.
  • The angular head design looks great and significantly increases surface area for better cooling.
  • Includes a Power Box muffler, designed with more volume for increased power while still being very compact.
  • A diagonally-placed needle means no remote needle valve is needed.
  • Same mounting dimensions as the O.S. Max .61FX
  • Advanced Bi-Metallic Liner process uses a double layer of platingmaterial rather than one thick layer. This helps the metal bond tothe cylinder and makes the plating more durable. Also, the platingprocess is more consistent, resulting in a more precise fit betweenpiston and sleeve for better compression and longer life.
  • Power Box muffler design provides more volume for increased power ina very compact shape
  • Angular head design offers increased surface area for better cooling
  • Ball bearing-supported crankshaft
  • 61A carburetor with diagonally placed needle valve eliminating remote needle valve placement
  • Two year limited warranty
