Product Description

AVIASTAR .46 2 Stroke Glow Engine Modern design combined with state of the art computer-driven machinery and superior metallurgy to create the finest 2 stroke model airplane engines. For instance, the connecting rods use the same aluminum alloy as found in some full size aircraft engines. Crankshafts are one piece hardened Cr steel. A specially developed "KK" bronze alloy is used for the conrod bushing which allows it to withstand high RPMs. Piston rings (1.2 - 2.0 in3 engines) are made of the same steel alloy as found in some racing motorcycles. The .46 in3 is true ABC construction. All engines contain high quality dual ball bearings. Of course, the carburetors are of a twin needle design for the best balance between power and fuel consumption. O-rings are used at all critical points to eliminate any possible air leakage. There's no lapse of power throughout the transition, making this a popular choice for aerobatic flying. Sig recommends 10% Nitromethane Champion Glow Engine Fuel with castor blend. Power ratings listed were obtained with FAI fuel (0% nitro) on a hot summer day with 85% relative humidity Specifications Displacement .46 in3 ( 7.53 cm3 ) Bore .886 in ( 22.5 mm ) Stroke .756 in ( 19.2 mm ) Practical RPM 1 900 to 16 000 Weight Ex.
