The Bell 430 is a stretched and more powerful evolution from the Bell 230. It is an American twin-engine light-medium helicopter built by Bell Helicopter and was formally launched in February of 1992. It is powered by twin Rolls Royce 250-C40B turboshafts that give it a powerful and smooth ride.
The Sikorsky S-76 was originally launched in March of 1977 but has since been updated and redone multiple times. The most recent iteration is the 2014 model with state of the art avionics and modern tech. The timeless exterior style has not been changed much over the years but had small updates here and there.
