How to beat BF109E7 with MC202 from higher altitude?

[bycomet]

Two aircraft with same engine and different flying characteristics, so I'm curious about the fight between them. I tried it in quick mission with Ace AI.

 

First, I used BF109E7, AI was MC202 at same altitude. It was an easy battle. Just two or three vertical turns and I was able to stay at AI's six.

 

Then I tried MC202 (0% oil radiator, 100% water radiator) to fight BF109E7. I knew MC202 wasn't good at turn, so I started at 3000m and AI started at 1500m to help me use BnZ tactic. I dived towards BF109 but soon I found problems. BF109 turned fast and pointed its gun at me during my dive. Its firepower was dangerous to me for a head-on attack, I had to roll away before reaching its gun range. Then I climbed away to commence another dive turn. But same result, BF109 already turned to chase me when I was climbing. It was another frontal attack which I had to dodge. I pulled up to prepare for the third dive and found...Damn! BF109 already climbed to my altitude. Although we were in opposite direction, if we both turned to each other, with slower turn rate, I would be at energy disadvantage! Just after two BnZ, a BF109 started from 1500m lower gained higher energy than me! I had to disengage with faster speed, the only advantage left.

 

This is a BnZ trick. MC202 can dive to BF109, but BF109 can turn and use its great firepower to force MC202 to give up attack. And BF109E7 is 300kg lighter than MC202, it loss less energy during turn and climb and finally it has higher energy.
