we have had R44 Raven IIs for 2.5 years now, the starting procedure i was taught was exactly that, follow the robinson flight manual. however all 3 of our machines are at different hours and all start slightly different.
but sometimes they wont start straight up... its the nature of machinery. we do a lot of tourism and the only thing my passengers have ever said about the R44s is the clutch engaging.. now that noise is not great for first time passengers...
