Os .65AX ABL w/E4010A Muffler

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
