I developed some hardware on this model using a lot of ideas generously contributed by folks on this forum.
I'll point out the bits that I did on this plane in case it gives someone a good idea.

The control surface hinges are straps of thin brass sheet wrapped around the leading edge of the elevator (and rudder) which is aluminum tube. The tube acts as a joiner for the elevator halves. The trailing edge of the stab is reinforced with 64th ply, and the straps bolt through the trailing edge of the stab using 00-80 hex bolts from Microfasters.

The tail skid swivels and tilts (but is not controlled). Skid is sprung with a spring, not bungee! The "shoe" is a piece of brass fastened with a bolt. THe skid tilts on the brass tube post using a bracket made of thin guage steel snipped from a paint roller tray. A bolt holds the steel bracket to the skid. The brass tube is drilled through such that the steel bracket is retained and allowed to pivot on a A piece of thin music wire. I may have a picture of this before covering....have to look for it later.
The tail is braced with Fireline using AL tube for ferrules and fish-hook eyes are used as attachment points.
I have more pics of the front and the UC parts, but I'll have to hunt for them at home. Anyway, none of this very "scale", but I think it looks cool!
