Tech Notes
 
NOTES FROM OUR TECH DEPARTMENT
This is the O.S. Max 75 AX ABL Aircraft Engine with Muffler.

FEATURES

Same mounting dimensions as the O.S. Max .61FX
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.
Power Box muffler design provides more volume for increased power in
a 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
