Tech Notes
 
NOTES FROM OUR TECH DEPARTMENT
This is the O.S. Max .55 AX ABL Aircraft Engine
with the E3071 Muffler.

FEATURES

Same mounting dimensions as the O.S. Max .46 AXII
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.
Angular head design offers increased surface area for better cooling
40K Carburetor with diagonally placed needle valve eliminating remote
needle valve placement
Two year limited warranty through Hobby Services beginning at date of
purchase
