At each new set of blades (i REALLY need those blade grips!) i have to use half turns to get them in track as well.
I can't figure out why it would be directional?! I tend to turn them that they 'line up' with the balls as best as possible, whilst keeping the blades in track.
I'm using a Protech flybar, and also had to change the lower linkage to fit the eflite blades.

Wolf, so you are flying again?! Great news! I might have read that already, but then i forgot .
