Good Morning Extreme,
According to my Log book, I was solo in R22 at 11.2 hours, and passed my test at 36.3 hrs, Then I started to learn how to fly, and am still learning new things about the H flying today, as for your question as to " How Easy", I think its purely down to the CFi and your ability to pick up how to control an unstable piece of kit, oh , and sweat buckets in the process!
My Regards
