Connecting rod for GF30 engines

This connecting rod is an RC-scale replacement component identified as OS4A005000 and intended for GF30 engine use on model platforms. It serves as the rotating linkage between piston and crank assembly and is offered as a factory-design replacement part.

Intended use is strictly within RC model engines carrying the GF30 designation. Installation normally forms part of engine service or rebuilds, where the rod is fitted during reassembly of the crankcase and piston assembly by an experienced modeller or technician.
