This video was meant to be uploaded a month ago and was delayed due to strange quality issues. (Basically I had a rough time editing and didn't put too much effort in this...).

In short this duel just shows how much better is the I-225 versus the Bf-109K-4 at low, to nearly high altitudes. However a stock I-225 has similar turn to a spaded Bf-109K-4.

(Fun fact: Roll rate increases with altitude...)
