Firstly , do not believe those who tell you it is best to have no flying experience before to start rotary.
Not sure where that one came from, but all three Services routinely give their future RW pilots upwards of 60 hours SEP before sending them to learn RW. While CFS is not the only fount of aviation wisdom, they may have learned that it saved money and/or time in the long run. It used to be more - I had 95 hours on Chipmunks and Bulldogs before starting on the Gazelle at 705.
