Insuber, we posted at the same time...
Your observations about overall performance are indeed valid.
I have passed Spitfires in a gentle climb several times in my Hurri. Now there is no way to know how the other pilot is managing his aircraft, but if both are flown equally that should never happen. And yeah the poor G.50 is terrible, about as bad as the Blenheim is.
We have a long way to go in getting these planes sorted I think. In the meantime all we can do is fly what we have, try to post our observations in as unbiased a manner as possible, and most importantly, have fun.
