Well, there is no need to have a handle to observe the performance of the AH 109s because the graphs can be found from the AH main page.
When I used to play AH, I used the F-4 and the G-2 most of the time as those are (were?) easy and well behaving planes for a beginner like me (and for the FAF skin of the G-2). There was no G-14 back then.
