You'll want to set them in line with the bottom of the wing instead of the top. That makes for a slight tipped up look when viewed from behind.
Only if they are "thicker than the wing" , right?
If they are exactly the same shape and thickness then top and bottom will all line up well. I'm shootin' for as close to perfect as I can , but realise that they won't be perfect. Many of them are not even straight on used RTFs.
