Hiya Happy1, been a while sir!
I agree with Pellick to a certain extent. I never B&Z with a spit IX though, however, I will use it's ability to fly in the verticals against A/C like the Zeke. The Zeke will turn itself inside out to get on your six, but.....and its a big but, it does not have the power to sustain a fight in the verticals with a SpitIX.
(which to be fair to Pellik is, I think, what he was trying to get across).
The biggest mistake most people make when against a Zeke (or any other pure turnfighter) is getting slow and trying to slug it out on the opponents terms. The Zeke turns on a dime below 200 mph. Keep the fight fast and he loses advantages very rapidly. Get him in the verticals, use a bit of "geometry" and it will seem to him that you are outurning him. In fact you aren't really turning "with" him, you are turning "against" him.
What I do is, put him in front of my wingspan. Once there I will do whatever I need to do to keep him there. I will try to keep him fast, I have a better turning radius at 250mph than he does.
Happy, Its really all "E" and recognizing what "E" the opponent has, what he/she is flying and how that potential relates to what you are flying.
ME109's: The only 109 you should really have a problem with is the Franz. This one can ruin your day as a Spit driver. It will turn pretty close to a SpitV in the right hands. (Eagler is deadly in the Franz). It has the power to follow you in the verticals, and it should be respected. The other ME109's...well feel them out (actually I recommend flying them a bit). They all have an amazing ability to fly in the verticals, but the only one I worry about is the Franz, because it will turn.
109's are notorious for being higher than you. Don'y worry about it. Just don't climb to them (they want u to do this). Make them come to you. Keep them in front of your wingspan, keep your speed up and they will come. Guaranteed.
Once you get them on your terms......Enjoy the Buffet!
In short, the easiest way to get a 109 on yer plate is to get him slowed down and turning. MAKE HIM FIGHT YOUR FIGHT.
Cheers, Hope this helped a bit
AND......<<>>> Happy!
