I understand line segments, rolls centered on lines, equal radii good geometry, wind correction and all that. The only thing other than what we are discussing im unclear on is centering and from what I read and watch centering is a non issue.

Ok. On my edge the wing drops and the nose follows, it just doesnt stall nose 1st. I'll work on getting the nose to drop 1st. Also how are these guys getting away with leading the direction of a spin to get the desired exit if leading the direction of the spin is a zero or at least a severe downgrade? There is a big difference between yawing the plane to maintain track and yawing the plane to initiate the desired rotation of a spin. I always understood that a stall was something the plane did, not something the pilot did. The pilot just follows the planes natural motion based on which wing goes 1st, that is determined by wind and lateral balance eh?



Getting off into the weeds here..
One of the big things I learned with pattern is you can yaw the plane all you need to as long as the plane maintains the correct track. IE a vertical upline with a crosswind. You can point the plane into the crosswind on the upline or downline and still travel perfectly vertically. Even though the planes centerline is slightly perpendicular to the track, the track of the CG is still vertical and not being pushed in or out by the wind. Or as mentioned yawing the plane to maintain a track parallel to the flight line when traveling straight down the box. Or I would think as you said the plane would enter the stall yawed nose into the wind to maintain track and then let the chips fall. This is not a downgrade in pattern and actually demonstrates expectional control, Im sure the same holds true in IMAC.

Thanks for the continued discussion this is very interesting and educational for me.
