yak cant outurn 109
Depends on the model 109, but with throttle control the Yak can stick with and even pull the nose ahead for a shot on a lot of aircraft especially at speeds 250 plus, though not sustained though. Once speed drops down near/below 200 it's time to break off,regain some energy (effectively resetting the fight) and come back in for a new merge.
