let me tell you
As a 9000+ hr fixed wing guy and a 100+ heli guy, I can attest, you will probably get yourself into trouble. I have made some mistakes that almost totaled the heli because I thought I could handle it. I knew I could handle it in the airplane and tricked myself into believing it was not big deal in the helicopter on that particular day.
For sure learn to fly rotorcraft, it is a great experience and, for me, some of the most exciting flying I have done, BUT be very aware of your short comings and lack of ability in a helicopter compared to an airplane.
I'm sure you know as well as I that it is much different when flying for fun vs needing to get there to please the boss.
