Flats hinges are fine. I have used them in a few planes. You have mor surface area ,use 30 min epoxy when gluing them.

Good flat hinges should be really strong.
I cut the slot with a hobby knife and then a small file when cutting into balsa. I used a dremel multimax to cut in the slots into light ply.
I'd tape over the slots and cut the slots back in through the tape leaving tape where you want to protect the covering from glue. Maybe a smidge of petroleum jelly or similar carefully applied to the hinge itself if you're worried it might come into contact with epoxy.
Running piano wire through the hinges is an option to make the surface easily removable.

Yup flat hinges work well. That's some solid advice from @Surfer Dude and @ThePledge .
I also like to pin the inner most and outer most hinge on each surface. Just push a T-pin through each one and cut it off flush on each side. Makes for an uber strong setup. Can't do that with Robarts.

Flat hinges all the way. Never had a problem with DuBros or any ARF hinge...

They already have the slots cut on this plane. Just got to glue them in. Do you glue one side of the hinge at a time? For example put all the hinges in the wing and glue them. Then put the aileron on and glue it?

Yup one side at a time. Let them dry. Then do the other side. At least that's the way I do it.

When gluing hinges, just remember to dry fit the surface and run it through its range of motion before the glue sets. For example, when gluing aileron hinges, put your epoxy or whatever glue you use in the wing hinge slot, install the hinges, then install the aileron with no glue on the aileron side of the hinge. Move the aileron through its range of movement to set the hinge alignment (ensures no binding), let dry overnight, then glue the hinge in the aileron the following day.

While your slots are already cut, this works well for future builds. http://aerobroach.com/
