When the attacker realises that he is unable to stay on the inside of the defender's turn, he relaxes his angle of bank a little, then pulls high. As he comes over the top he is inverted, looking down at his opponent through the top of his canopy. His speed falls due to the climb, and this diminishes his radius of turn. The Ig of gravity is utilised by turning in the vertical plane, which reduces the radius of turn still further. The attacker should then be well placed to slide down into a firing position.
The high-speed yoyo is a very difficult maneuver to perform well, and demands perfect timing and precise execution. If it is commenced too early, the defender can counter by pulling up into the attack. If started too late, the attacker is forced to pull up at an excessively steep angle to avoid overshooting. This allows the defender to disengage by diving away. A common fault in executing the high-speed yoyo is not pulling the nose high enough. This can result in the attacker ending directly above the defender. Some pilots find that they obtain better results from a series of small yoyos than one large one. A variant on this maneuver, used to prevent overshooting or to reduce the angle-off, is the rollaway.
