CA Hinges are easy to install, I'll grant you that much.

In those three videos, there's one sentence that stands out more than the rest. "Installing CA hinges in a plane is the same thing as adding an expiration date."

CA hinges are nothing more than a single sheet of plastic that flexes - a LOT. They'll give out. Many factors affect that - the amount of flexation, oils, cleaners, fuels. Maybe just one will fail, giving you time to change them out, or maybe all of them on a surface - and then maybe - down it goes. Whatever kind of hinges you install doesn't matter. How well they hold out matters most, especially on a plane this size.

Maybe I could suggest that you use Robart pins (or some other pinned hinge) on the tail feather surfaces, particularly the elevators, and then if you want to use the CA hinges on the ailerons, there would be less danger should you lose one. The Stearman is a nice bird, not to mention the radial you're talking about; it would be a shame if a surface failed and the whole Bipe was lost.

And yes, you're going to love this bipe. I love mine just sitting still on the table! It's just beautiful.
