Gruesse Reely....
a buddy of mine and me are leaning to get us a PPL-H each
.......In a BO 105..... are you off your rocker??? Seriously, not that I'm jealous or anything, but I wouldn't recommend that. Learn to fly in something smaller and less powerful... It will teach you to respect the machine and the power available. You'll be thankful for it later. Once you've got a PPL do a conversion onto something in between and then onto the 105...
I have instructed quite a few PPL's in my time and have taught some who could afford to buy big machines straight out.... we always recommended starting small and work your way up.
If you do a PPL you will have to register the 105 with a school who will charge you, and pay an instructor and some possible other fees, so it might work out more expensive than doing it in a 22 or 300...
