Stall Turns and head winds

[Gray E Fowler]

Keith

The thing that may be messin' wid yo head is thinking that the plane 
itself needs to be at a 45 degree angle (cuban 8). Into the wind it should 
look less than 45 and with the wind more than 45. The "abruptness" is 
because you have yet learned to anticipate the need to change heading and 
then are doing it a little late requireing the abrupt change to maintain 
center-geometry etc. Just do not expect me to demonstrate this........If I 
ever do it is luck.
The stall turn when done correctly rotates on the CG so the nose into the 
wind on the way up translates into the nose into the wind on the way down 
when the rotation occurs properly. If you do a mini (or maxi) wing over, 
then it gets ugly.Without wind practice getting that stall turn to rotate 
on the CG and that will help alot when the wind is blowing. Also remember 
that more nose into the wind is required as the plane slows down. When you 
do the rotation at the theoretical stall, the wind will blow you 
back.....which is not supposed to happen but does.

Actually it's giving me a challenge! 
 
Honestly I was happy to have the windy conditions yesterday as I was able 
to experiment with different techniques to try and get the maneuvers 
correct. During my practice/experimenting numerous light bulbs went off in 
my head and I improved slightly, unfortunately there are still a lot of 
dark rooms ;-)
 
On the Cuban eight I'm still trying to figure out how to drive into the 
wind and keep the loop round without making the plane's transition between 
heading into the wind and turning down wind look too abrupt. I'll have to 
get you to watch me after Nats.

OK, I've got another question about head winds. 
  
When performing a stall turn I know it's necessary to keep the nose of the 
plane into the wind on the upline so the wind does not push the plane 
backwards, but what's the best way to execute the actual stall turn 
itself? When I tried to do the stall pivot with the nose still pointing 
into the wind it looked terrible and was VERY difficult to get it to pivot 
straight to the side. Obviously with the nose into the wind the rudder 
will not make the plane fall perfectly to the side but will also cause it 
to rotate. Because of this I tried backing off the of the wind correction 
and pulling the nose straight up right before performing the stall 
rotation, but when I did this the plane would drift backwards. 
  
I'd like to hear how others handle this situation to score high on stall 
turns in a heavy head wind. 
  
BTW, I had a good time flying in the wind today :-) 
  
Thanks,
