Yep, vertical stab is perpendicular.

What size prop are you turning with 91FZ?
If there is no modification necessary to add more side thrust, go ahead
add more.  It should not hurt anything.
 
I am not sure about this, but have you checked if the vertical stab is
perpenticular to the horizontal stab & the wing? I think I heard about
vertical stab not perpendicular to others causing something.
 
I usually bank near to 90 degrees.  this way the elevator is actually
working as a directional control.  
 
I also tried 45 degrees up & downline with half roll for CG.  (I am not
sure where I learned this.)

I've got 12 flights on my Quest with YS91FZ.  In a vertical climb the
plane yaws to the left.   I have increased right thrust to where I
believe it is more than 2 degrees but still have this towards the top of
the climb..  Could something else cause this problem?
 
In the trim chart for balance it says to put the plane in a 60 degree
bank.  If the nose drops, add weight to the tail.  Does this mean that
when you make the bank, the nose of the plane should not drop with no
back pressure on the elevator?
 
 
TIA,
