A few things.
First of all, very nice ride. I often sandbag with friends who own planes...I pay for half the gas, we go fly, I get stick time.
Winner, winner, chicken Avgas dinner!
Seriously, you did very well.
Concerning you as a low time pilot and owning a "complex" aircraft, I'd like to echo some earlier comments: In military flight school(s), they take folks who have never flown before and put them in complex, turbine powered aircraft and they solo after 14 flights. You can do the transit very smoothly.
I've flown a whole bunch of different air vehicles, from trainers to jets to helos to multi-engine, etc. The key for you will be recognize the difference between a 172 and your new ride.
Handling.
Speed.
Gear.
Familiarity.
Pay attention to the differences and the skills you need to hone from the 172 to your ride:...the Bernoulli's don't change
When I was the Chief test pilot at the Sikorsky factory, I was checked out in UH-60L Blackhawks. I already had almost three thousand hours in SH-60B Seahawks.
The hardest thing for me in the transition was to empty my reflex response to SH-60B emergency procedures and adopt the UH-60L emergency procedures: Same basic airframe but very different methodologies to handling aircraft emergencies.
It is funny what "muscle and mental" memory lay just beneath the surface of our responses.
Anyway. Well done. I'd love to split some fuel with you some day.
