from the pic it is hard to tell what you're trying to show...But the best fix is to glue the break back together.Then get a piece of the same materail and glue that "doubler" along the break

do you have access to some balsa and some covering, for repairs!
if so, I would start by removing the elevator, should be replaced with a new full piece, if not, then try and straiten out the pieces, by putting them back where they belong!
depending on how good a fit you can get, you might be able too apply some epoxy too the joints! then tape in place while it dry's!
if you hafta you can peel back the covering, just enough to reveal the affected area, then tape back in place! scotch tape or packing tape is always good in this situation!
that should be enough to get you started, go ahead and post more Q's as you have them!

P.s. puts some sox on!

Another option would be to butt glue the pieces back together and use some sheeting over the stab. Then use flying wires. But for me, I'd replace the stab.

I have access to balsa and covering, but don't have the plans to rebuild the horizontal stabilizer (I bought the plane already built)

ok is it a slab stab? " solid balsa"

or a built up stab? " sheeted sticks"

not having the original plans, isn't the end of the world! we can rebuild, we have the knowledge!

if it's a solid stab, then that is too easy, just get some balsa the same thickness, and trace the out line of the stab, running the grain of the balsa, the long way!

if it is a built up stab, then you still need too copy the outline, and dissect it, so as too figure out the size wood used! and we will go from there!

Well then you have two options, you could try to re piece it together, or you could just piece it together best as you can and trace it onto a solid piece of balsa about the thickness of the sticks. Sand off the edges, then cover, and glue it into place. Then it will be stronger too. It shouldn't effect the weight much, but you may have to add a tiny bit of weight to the nose. Or you could cut a bunch of holes in the new stab you built to lighten it before you cover it. The possibilities are endless.

epoxy would be best! and like I said in the beginning, it still looks like your gonna want a new elevator!

but it looks like to me, you could use some sticks the same size, and make some gussets! just keep in mind, too try and keep it as strait and true as possible!

you can either, throw it back together, and just fly, or go about redoing it all together! your plan is right there, and too me, I would throw some gussets in there and fly!

Ya, I always use epoxy on my tail feathers, some people use thick ca or even medium. Epoxy is by far the most durable and permenent.
