The Bell 47J Ranger is a single-engine single-rotor light helicopter manufactured by Bell. It is an executive variant of the highly successful Bell 47. Another fact about this helicopter that made it famous, is that it was the first heli to carry the President of the United States. Just north of the USA, Canada decided to use it in the Coast Guard role, to much success. Here is a scale model of it, at the 2016 IPMS Heritage Con, bearing the registration CF-CAF.
