Have not flown a L3 or L4, all we got is an LR which is nicer to fly than a jetbox but still, after 3-4 hours of flying in the LR my butt is hurting like there is no tomorrow. Put me in an AStar, I will fly all day......
Ever since I got into the AStar, its all I want to fly. Almost all the customers I fly with agree but are limited on a certain budget that allows them only to fly either a jetranger or longranger.
I grew up in Switzerland and there the most successful Helicopter would probably be the Alouette 3 SA319B. The Alouette 3 made mountain rescues possible and saved probably tens of thousands of peoples lives the last couple of decades.
The most successful Helicopter in the world most likely is the Bell 206 Jet Ranger but it is definetly not the best or the one Pilots favour. (Me, I hate the jetbox
)
