Tech Notes
 
NOTES FROM OUR TECH DEPARTMENT
This is one of the O.S. FX series of high-performance engines. This series
of engines is used in sport and aerobatic aircraft. The FXs are designed to
use a muffler or tuned pipe.

All FX engines are covered under the O.S. Max Two Year Warranty.

FEATURES

1-piece crankcase
Twin ball bearing-supported crankshaft
Schnuerle porting (AKA Schnuerle scavenging)
Advanced Bi-Metallic Liner. This process uses a double layer of
plating material, rather than one thicker layer. This helps the
metal to bond to the cylinder, and is more durable. Also, the
plating process is more consistent, resulting in a more precise
fit between piston and sleeve, for better compression, longer life.
Side exhaust with muffler with rotatable exhaust outlet
New carburetor with remote needle mounted on the backplate of the
engine (to keep fingers away from the spinning propeller).
Aluminum backplate.

INCLUDES

One Expansion style muffler (#E-4010) with screws
One Assembled engine with carb
