Technology has advanced so much since light helicopters were last being designed that it is now possible to build a turbine engine that offers high performance at a reasonable price point – this is one of the reasons behind Hill’s decision to go this route.

Piston and diesel engines were researched but were found to be lacking. Have a look at why other types of engines proved unsuitable, and what led to the opportunity to deliver a modern, electronically controlled, efficient small turbine.
