The YS120 Engine with Matching Pipe combo! Make your heli scary again.

YS information:

The all new powerful YS 120SR Helicopter Engine is built with the same mounting as 90-class engines, which makes it easy to add more power to existing 90-class helicopter platforms. The 120SR is proven with factory-preset regulator for consistent, reliable operation — positive fuel flow during all conditions. Its now larger cylinder head has better cooling capabilies. Horsepower is also increased with the steel-lined back plate for minimizing drag.

The mounting on the YS 120SR is of the same dimensions as the YS 91SR. So an engine upgrade requires no modifications.
