<DIV><FONT face=Arial>With your .40 size plane in 20+ MPH, its the equivalent of
flying a 2M plane in about 30+, so you are more challenged in the wind.

<DIV><FONT face=Arial>Thrust is a big factor. Running 30% in a DZ
helps a lot.</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>One of the biggest counter-intuitive things to do is add
throttle going downwind before a pull up. One would think to keep the
(ground) speed constant, you cut the throttle to quarter or less going downwind
and increase throttle into the wind. But lets take a maneuver like a cuban
8 entered down wind. If you enter the pullup at quarter throttle basically
the plane has so little (airspeed) that the wind just pushes the plane
downwind and you never make it back to get the half roll crossover centered on
the pole. If, however, you pour the coal to the fire as you pass the
center pole, so you are full speed and lots of energy before going into the
first 5/8 loop, it "carves" the radius, allowing you to come back at the center
pole on the 45 degree line. You also should start the pull a little sooner
than you normally would, to adjust for wind drift. Crosswind? Where
do you start correcting? Before reaching the center maneuver area. you may
have to add a little opposite rudder to keep it from weather-vaning too much,
remembering to ease in ailerons as its looping around (to keep the wings level,
as the crab angle at one point of a loop segment will put the wings off as the
plane comes around). Similar issue for the F03 thing with the zip-tie
figure (last maneuver) adding throttle as the thing is coming down on the long
45 degree line is counter-intuitive but helps keep the "line" at 45 while
minimizing wind drift.</FONT></DIV>

<DIV><FONT face=Arial>A story- One of my best wind corrected flights ever, in
fact my most skilled flight ever in the wind, perfect wind correction, was my
worst scored rounds in the 1996 Nationals. See, prior in that round, the
wind was calm so I lowered the nitro to get a nice slow, smooth
presentation. When I was in ready box 2 the wind picked up- by the
time Dean Koger was half way through his flight, the incoming front
(thunderstorm) was blowing about 15 straight in. I went up and put on a
show. All my lines were fully wind corrected, sometimes 20 to 30
degrees. I was so proud of the fact that I was able to wind correct and
still maintain geometry and distance out throught my flight. How did it
score? Lets just say I went to the hotel that night and did some hard
thinking. What I realized was that a plane that only has to correct 5 to
10 degrees will present much better than one 20 to 30 degrees. It presents
better and actually makes it easier, particularly in the loops and radius
segments. How to reduce the wind correction? Power and energy
management.</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>Final hint for the day, stall turn. Wish I could
collect a dollar for each of the folks I coach whose maneuver score
improves by more than 2 points in a crosswind. Ever see a plane do a stall turn
in a cross wind as if there isn't any? Three things to do. First you tilt
the plane into the wind as you pull up into the quarter loop. This wind
correction is almost not discernable. As it completes the quarter loop,
add a touch of opposite direction rudder (to staighten the plane).
Remember you are at max power here to minimize the crab. As you approach
the end of the desired vertical line, reduce the throttle quicker than you
normally do, but ease in, thats right, more opposite rudder. Now not so
much rudder that the plane starts getting pushed by the wind, but
just enough to minimize the (natural crab angle) that planes develop when flying
a (ground reference) vertical line. When the airplane stalls you let go of
the opposite rudder and ease in the same rudder for a nice clean stall turn into
the wind. Now here is the clincher. Add a click or three of throttle
over the top as it comes around. Under normal circumstances, it would
cause a major downgrade with more than 1 1/2 wingspans, but in the crosswind the
plane (with respect to the ground) does virtually a pivot on its
axis.</FONT></DIV>
