"The most complaints I have seen about this plane is inserting the zarms into the round holes."

You hit the nail on the head. I kept busting the little plastic z-bends while trying to snap them into the control horns, then waiting for replacement parts trees to be shipped out. I was also frustrated by trying to glue the Cap 580 together using thin foam-safe CA and no accelerant. It seemed like it took forever for the glue to set.

I thought I was the only one who got frustrated trying to build a FlatOut, but I ran into several other folks that I fly indoors with who had similar complaints. Difficult to build, pop-out control surfaces were fragile, etc.

I finally asked a club member who routinely scratch builds flying wings and park flyers out of blue foam if he'd mind putting my Cap 580 together, and he said he'd be happy to do it. He had it together in a couple of hours.

Some folks can build the FlatOuts without any trouble, others find them difficult to work with. I don't know what particular skill set that I am personally lacking, all I know is I can slap together a Thunder Tiger Profile EP foamy together with ease, while Great Planes Flatouts leave me confused and frustrated. If you're a good builder, give the FlatOuts a try. If you're not an experienced builder, the Thunder Tiger Profile EPs may be a better choice. That's all I'm saying.
