I don’t have the F-5E or the M2K, so I wouldn’t know.
In fact, I have what is probably considered a short list now.
Ka-50 (which after almost 10 years including BS1 I have still never used the autopilot or 90% of ABRIS, it’s just a moving map or Shkval repeater), A-10C, FC3, CA, P-51 (barely touched), F-86 (barely touched), MiG-21 (barely touched), Viggen (barely touched)…I think that’s it. While the Mustang was a gift, I bought the rest and still wind up flying the older planes the most because I know them and when I get a chance to fly I tend to gravitate towards flying a mission vs learning a new plane…especially when I’m flying MP. I want to learn the others, but I just haven’t had time.
I did have 21 taxiing down cold, but never got past using the guns. It’s been so long now I’ll need to start from scratch.
