<DIV><FONT face=Arial color=#0000ff size=2>Thank goodness judges don't have a T
& B ball in a panel in front of them to watch how many are skidding through
the air.. grins.. I have always felt if all things are pure the pattern
airplane in true corrected crab maintains it same speed when pulling to vertical
and the crosswind component stays constant then no further input is needed till
your speed starts to decay when pulling vertical. What many are doing is
flying one wing low when in level fight then when they pull vertical have to
sneak in some extra correction for pulling a highly visible vertical to the
judges. </FONT></DIV>

answer on using aileron during a radius, for the purpose of wind correction,
is that if you are NOT using it is a downgrade(able). It’s
impossible in every way to use only rudder through a radius actually keep the

<P class=MsoNormal><SPAN class=EmailStyle23><FONT face=Arial color=#993366
size=2><SPAN style="FONT-SIZE: 10pt">This has been an interesting
discussion. The airplane dose not establish a crab angle on it’s own when in
the air. The airplane has a crab angle in horizontal flight and when it is
pulled vertical the wings will not be perpendicular to the flight path
without a roll correction. The need for the correction will be apparent and
automatically applied prior to finishing the radius. When a roll input is
applied with elevator it changes the heading in the direction of roll,
(think barrel roll) in this case into the wind as it finishes the radius.
Most of the time it will be excessive requiring a little opposite (down
wind) rudder correction unless the upwind wing was high entering the
pull-up. Once the airplane is leaning to one side in a vertical the lean
will increase and is especially noticeable as it slows. Some increase is
needed to maintain wind correction and the need for opposite rudder to
maintain a vertical track depends on how rapidly the airplane is
decelerated. Most of the time I will try to apply some down wind rudder with
the roll correction at about 45 degrees, before the need becomes visible as
it is nearly always required. In short just point the airplane in the
direction you want it to go and stir the sticks as
necessary.<O:P></O:P></SPAN></FONT></SPAN></P></DIV>
