A military trainer is hardly a high performance aerobatic aircraft!
Tell that to Julie Clark and her T-34.
Or anyone who flies a T-6, T-28, T-33, T-37, T-45, etc. They're all high performance and aerobatic by design and classification.
I wonder if Bob Hoover needed stuff on the wings of his Shrike Commander...

Talk about restricted visibility. Whew.
BTW,I know the reason they have them,I merely stated this to point out that pilots often look left or right for reference. You stated that you didnt need to or found it of little value.
I said it was useful to look around but not required. I know my orientation without looking around because of the picture in my head. I look around constantly in flight but I know where my nose is pointed without looking sideways (or elsewhere). I also have an AH (Artificial Horizon) mentioned earlier in a pinch, but again, hardly ever used in this game, which is 99% VMC/VFR.
