I believe it was Pedro who told me this, and when I tried it. It worked great, so thanks Pedro for this. But when doing that mission, just stick close to his six, knocking 109s off, and you should have no problem. When I did it, he got like 6 109 on his tail (not at the same time, but different times) and not once did those 109s touch him. Maybe because I'm such a great Yak pilot, I dunno
