Angrist - Your right about the verticle scissor.
a "true" verticle scissor is a jet plane maneuver. WW2 prop planes do not have enough power to do a "true" verticle scissors.
What most people here are refering to as a verticle scissor is actually a rolling scissor that includes zoom climbs with each pass. This kinda looks like verticle scissors but it is carried out in the horizontal meaning as the fight progresses you are actually moving horizontally not strait up.
See this link. It has a short explanation and nice graphics of the "verticle rolling scissors" as it is correctly called. Which I believe is what you are reffering to in your beggining post.
http://combataircraft.com/tactics/index.aspxI would like to point out an exception to my statment above.
The verticle rolling scissor can be "partially" done in a superior climbing plane such as the 109k4 or spit16/14. HOWEVER it can only be sustained for about 3 or mabey 4 verticle rolls and when you get at the end you will be at total stall.....defensless. If you do not deny the shot you will be dead. If you stall first you will be dead. If the bogey follows your move turn by turn you will be dead.
When I do this maneuver the goal is not to create an overshoot but to create stall condition on the other plane----basically its a rope. In addition I will take the first verticle turn in positive G and then the next one in neg G. This means "pulling" on the stick to go vert then begin a roll still going strait up. Complete one 360 roll and at the completon of this still going strait up "push the stick forward gently" and begin the second roll with the belly of your plane facing in ward - so your canopy is now facing out. Complete a 360 verticle roll and then pull back gently and roll the other way into positive G normal barrel roll at the top.
The bogey will attempt to get a shot on you the whole time. To do this he must pull lead. When you go to the NEG G roll (canopy out - belly in) he will be facing the wrong way. He will try to flip over in the verticle at near stall which will make him flop over and force him to dive out. It is at this point you have him.
I guarrentee if you try this yourself in practice you find out how hard it is to actually do. It takes a lot of practice. But if you learn to do it it will be one of those moves that gets the "how the freak did he do that" response. HEHE.
In fact some times you will end up stalled out together just feet from each others plane. IF you are upright (canopy facing up) and he is inverted when this happens the bogey had no choice but to dive. All you do in snap roll righ then and fire. You will be mear feet from him and cannot miss.
The goal of this is to make the bogey loose control of his plane while flying vertically. It is muuuucccch more difficlult to maintain control of a near stall airplane while pointed strait up becuase it be very disorientating. You MUST pay attention to your planes attitude and fly perfectly. The other guy is just trying to shoot you and is not paying attention to his aircraft which is why it works.
It is possible to create an overshoot this way if the bogey has a superior zoom. By pushing the neg G barrel roll immediatly upon going verticle he will usually fly right through the barrel roll and you will have a shot. But be carefull about following him up unless you had a ton of smash to start with. OR if you did the first neg G roll very tightly you can follow but only if you did it perfectly.
I will try to get this on film tonight and post it here
