I tried it out.  Its seems OK.
For me, not a replacement for AH.  I can see where people could get involved in it just as I have with AH.  
To me the planes seem sluggish.  Is this bad? Is this more realistic?  Hell, I dont know!  I am used to AH.   I guess if I flew it longer I'd get  used to it.  It is truely a individual like or dislike.
I had good connections and Frame Rates.  I will fly it more today and tomorrow.  I asked questions on the radio and got quick answers.  Not very many flyers on.  I was the only RED in one arear and was quickly set upon by 5 greens.  I died just as easily as I do in AH.   

Nothing bad to say for I found nothing bad, but I cannot see myself changing from AH to fly it.  I am too used to the AH  and been in this community too long.
