The R22 is by far the most popular machine, granted. but one must ask why?? The ONLY reason is because of acquisition price $$$ its cheep!!! end of story, its cheep & its nasty. Beginning & End of story. The reality is the 300 is a far superior machine but requires a skilled engineer to maintain which are less available especially in remote areas. There are soon to be some very nice new contenders being certified to compete with the so called safety record of the Robinson. Safety comes at a price, less price = less safety
