I'm putting the flaps on my 360 and have a couple questions to the experts.

The spar on the bottom flap skin is shown to be in front of the foam insert
on the blueprints (J). But that's not possible on my bottom skin.

Is it alright to put that spar on top of the foam insert? This will shorten
the phenolic insert (bellhorn) some.
If the promximal end of the flap meets the fillet of the fuselage (top to
top), does the distal top skin of the flap tie with the top of the aileron
skin in this condition?
Does in-trail for the aileron mean you place a straight edge tangent to the
top skin TE of the wing and the top skin of the aileron is tangent to the
straight edge too?

These are fairly simplistic questions, I know, but sure want to do this
right. Thanks all.
