What a twin.
If safety is an issue it has the best single engine performance of any of the usual suspects (turbine excluded of course).
A true gentleman's transport.
Not the cheapest to run by far, but ticks all the boxes.
Counter rotating props are a real bonus. Most are not certified for flight into icing - give these a miss if part of your rmission profile. Everyone says the fuel system is complicated - rubbish.
I wish I had more time on type. My friend owned one for many years and I loved the 310 - hopefully someone will be along with far more experience than me to better inform you.
For sure I will come and fly it with you!
