My best is definately a 7v1 with me defending a field. I was the only person in the sector, the 7 of them flew as a large clump towards the base. This was in the islands map, I was on the northwestern Airbase on the Leftmost home island. The enemy came from the Southeast, I was North of the airfield at about 15k feet or so. I came in from behind, bounced two of the rearmost planes in my first pass, then headed back up. The other five kept going. It was 3 spits and 2 F4U's- I honestly don't even think they knew I was there. I bounced another F4U as he made his run into the field, and shot his tail off. The other F4U and one of the Spits went after the VH and field ack, while the other 2 spits went after me. I went up and rope a doped one, went past the other one and got the last f4u as he was coming around for another pass at the field ack. The other spit got hit by ack and went down, and I managed to get the last spit in a heated fight right over the field. I landed with 29 cannon rounds out of the 620 I started with (190A5). I rearmed and upped again, and caught another F4U as he came in alone to mop up the field. Then I called it a day and landed.. got something like 19 perkies for that sortie. THAT was my best sortie ever, I really doubt if I'll ever be able to top it.
