Just my opinion so its worth what you paid for it....F3 is an advantage of immeasurable proportion. Not that people cannot make those shots internally, its that you don't ever miss externally once you get good at it AND it allows you to see a 180 degree view, unimpeded around you...SA on steriods.
I flew the first 1.5 years in the DA and for about 8 months used F3 without fail. HUGE difference guys...once you get used to it shots fired are shots hit....guaranteed with any practice at all.
Lastly, my first DAY in the game, GhostH was the trainer in the TA and he was trying his best to help me get an F4U-4 OFF THE GROUND...(wrecked it on takeoff 21 times in a row...my 8 year old son counted them outloud and then proceeded to tell me to listen to the man in the computer because you're not good at this Daddy) and when I finally did he advised me strenuously NOT to go to the DA or the MA until I got used to the flying because it is humiliating to get shot down repeatedly...he was right so I switched to F3 after listening to some guys talk about it. My point is that I would have been MUCH better off without F3 as a training tool...I had to re-acclimate myself to everything once I decided I wanted to fly a sim instead of play Galaga.
I made some real good buddies in the DA...they fly their way which is arcade gamey to me. I don't know any WW II pilots that flew 200 feet behind their plane on a tether of some sort with complete control over their a/c...lol. It should go because new folks find their way into that arena and learn the game wrong. If I hadn't listened honestly to Sunbat, Hlbly, Dodger and MugZ I would still be in there or off the game...honest truth.
