Films do show flaps, don't they? I never saw yours come out, and that's bad for this kind of fight. I also didn't see any throttle modulation on your part. It was either military power or WEP the whole way. The 109 is considered an expert's plane for a reason: you need to be on top of your flaps, throttle, and rudder at all times. Doing less than that isn't going to cut it against an opponent who merely has to drop a couple of notches of flaps to transform into a prop-driven Harrier.
At around 20 seconds, you start to descend from the initial "up" part of your rolling scissors. This is where you need to drop flaps and ease off the throttle. In fact, in anticipation of his next move (which is to drop in behind you), you need to be going as slowly as possible. The 109K-4 is a fast aircraft, and it is easy to go too fast with it, which seems to be what happened to you.
Yeah, I don't think I did put flaps out, something I'll have to remember from now on. What gets me there is that it's not a situation where I
feel the need for them, so I don't think about dropping any. I'll just need to force an adjustment to my thinking there.
I had actually worked throttle earlier in the fight, to get to the point where the film starts. That is a
feel thing too, also one that I need to redress. I guess I got so obsessed with getting a shot, once I got behind him and that close, that I just let the actual flying of the plane go.
I need some mental work here more than anything it seems.
Lessee, more lag persuit, less speed and more flaps, snap roll at the top rather than just flowing around, don't get fixated and forget to work the aircraft.
Have I left anything out?
Edited to add, Thanks for all the help guys, I really do appreciate it.
