ummm...... not to sure about "sometimes extremely wild maneuvers won't be for last ditch"...... most would not even be thinking of doing something extreme or wild unless they had nothing left in their sack to pull out for a defensive situation........
even though pulling off an "extremely wild maneuver" might grant a person a shot opportunity more times than not....
I must insist and say it is last ditch still , or at least it is not an appropriate way to be approaching an engagement and it should not be taught as a way to obtain a setup to pursuade your opponent into thinking he has a shot then trying to turn the tables on them by pulling some wild maneuver on them.....
These things are good to know however if you can become proficient in exercising them, if your are competent enough to make the maneuver work for you say 95 to 99 % of the time if you find yourself in an akward position and are in a "MUST USE NOW" situation......
now on a different note: I have kept going back and looking at that Bf109 youtube film/video link of Krupinski's....... and I can not find where he did any tail slide,am I looking at the wrong link? I see Krup roll inverted and then do what seems to be something similar to a controlled inverted flat spin but he seems to recover from it exactly when he needs too ........ almost as if he has set and practiced that maneuver over and over 1,000s of times.......... that is how smooth it looks like he performs / pulls it off......... it would be nice to get the RAW AH Film of that you tube video......... to be able to see more of it before that particular engagement........ that was one heck of a shot, or Krup has one of those golden horseshoes hidden somewheres
BAR, if you would like more info on those Flat Plates and their use in AH, try doing some more searches on the boards..... that topic has been popping up for several years everytime dogfights or Battle360 or Wings of the (country goes here) episodes run on the History or the Military channels on TV......
hope this helps
