I liked reading your review - it was great with all the relevant details.
As for the JF 152 - I was tempted to get this for a little run around while I get more familiar with Vatsim, as it's nice and slow with all the relevant radios and dials at your fingertips.
I hesitate though, as the price is a little steep - if you compare this to an A2A aircraft the A2A aircraft blows it out the water IMO, and for an A2A aircraft you only talk an extra fiver.
I think if it goes on sale in the future, this one will be in my hangar, as I really do like Just Flight.
