Best set up for Aileron Spades??

[Parky109]

Morning Everybody!
Im just fitting my spades to my new wings and was have a geeky aerodynamic question!!
In the ideal world should the spades have the same dihedral as the wing (so they areparallel with the underside) or should they be level with the ground / aircraft level)
I can see that in the extream case if a spade had lots of dihedral if side slipping they would create a input to the aileron controls to roll into the yaw? Maybe we dont want that in a aerobatic aircraft??
Ive seen (i think extras) spades that have a huge amount of dihedral rigged, but cant remember if it was with , or against the wings dihedral.
Thanks for you help!!
Here is a picture of work so far!!!
