stilton, could I suggest you start with a look at the US FAA 'Helicopter Flying Handbook', one of many very useful documents available for download on the faa.gov website?
https://www.faa.gov/regulations_poli...ying_handbook/
Download Chapter 10 and have a look at the section titled 'Running/Rolling Takeoff', which starts near the bottom of page 10-3.
There is a corresponding section in the Helicopter Instructor's Handbook, page 11-4, available on the same website:
