Finless videos are great and for sure you can start with the numbers posted in those videos (Maximum and minimum pitch clearances), with some experimentation time you may change the settings to your very personal choices just keep in the pitch window between the minimum and maximum parameters. I am really new in the Heli hobby I have been flying RC Planes for years and mechanics are some quite different but very understandable and I have set the Idle 1 with no problem although I have not used yet because of my limited skills by now.
Have Fun!!
