I have also had a chance to fly both the JNP Corporation Sim as well as the Red Bird and find the JNP to be a far better product than the Red Bird.
Based on the Beechcraft Baron, I found it handled exactly like a Baron would. Also the assymetric training it was able to offer allowing the pilots to confirm identify and feather the inoperative engine and actually have the control forces to support their actions was unbelievable.
I can also verify that what Ebby1028 is saying, it is CASA approved and there are a few companies who have purchased one in Australia and are currently using them for IFR renewals.
Best thing to do would be to ask the guys who are operating them yourself and see what they think of it... I am sure they would be happy to talk about it.
