I started flying helicopters in my current army career for 16 years and then went to fixed wing. Flying helicopters is something that is harder than fixed wing. The helicopters you will fly have to be flown 100% of the time, no trimming and picking up a sectional and opening it with two hands. To be a safe helo pilot you need much more than the minimums and I would say you are barely safe then.
In the Army we get guys out of flight school with 150 hours in helos. They are marginal at best as far as their abilities. They do not get very good until north of 300 hours. The US Army has the best helicopter training bar none hands down, a civilian operation in my opinion can be good but not nearly as good as what the Army does. One thing you will have already is your "air sense" but you still need to master the helo. Now a big difference is the way we fly helos in the Army is way different than most civilian operators so there are differences.
My opinion and bottom line is it takes many, many more hours to be a safe helo pilot over and above the FAR minimums. There are just too many things that will kill you. Just look at Davey Allison, had lots of money, good training, but still lacked experience and that killed him quick. Now you can say that about airplanes also, but until you have flown both you will not understand.
