Ex. Muffler 13.4 oz ( 378 g ) Power 1.66 hp at 16 000 rpm Shaft Size M 7x1 Muffler included Sig recommends 10% Nitromethane 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 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. Cylinders are made of a special heat treated Cr steel alloy to insure a hard and true cylinder that will not distort at high temperatures. Piston rings (1.2 - 2.0 in 3 engines) are made of the same steel alloy as found in some racing motorcycles. The .46 in 3 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. T's no lapse of power throughout the transition, making this a popular choice for aerobatic flying.We ship worldwide & combine shipping!
