e.g. the connecting rod in the Aviastar series uses the same aluminum alloy as the engine of this CJ-6. ( A Chinese primary trainer owned by one of Aviatronics' founders , Mr. Frank Cheung )


Specially developed "KK" bronze alloy is used for the con-rod bushing . A tough alloy to withstand high RPM.

The same steel alloy used in racing motor cycles has been used for our piston rings.

The cylinders of all Aviastar engines are made of Cr steel alloy with special heat treat process to ensure a hard and true cylinder which will not distrot under high operating temperature.  All cylinders are ground to the closest tolerance and manually honed to perfect roundness.
