| Aviastar 2-stroke Glow Engines |
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. 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 in³ engines) are made of the same steel alloy as found in some racing
motorcycles. The .46 in³ and .53 in³ are 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 throttle transition making this a popular choice for aerobatic flying.
KAVAN recommends 10% - 15% Nitromethane Glow Engine Fuel with 20% castor oil blend for the .46 and .53. Power ratings listed below were obtained with 15%
Nitromethane fuel on a hot summer day with 70% relative humidity. |
