I've only flown the early version with 4x7.7mm machine guns, but besides the weak armament it's a decent aircraft. To me it compares well the 109F: a little slower but with a better turning circle. The ailerons and elevator are responsive at high speeds, and, IIRC, the engine torques to the right!
Keep in mind I have about one hour of stick time in the Iar-80 in Il-2, trying to shoot down Il-2s in one of the "Skies of Valor" setups.
