Great job, Bald Eagle;
I like your horns. I usually do the same where ever I see a need for it. I just recently replaced the G10 horns on my Yak with my own, home made CF horns. I have not installed the backing plates, yet. I don't even know, if I really need them. The footing of the horns are so deep into the control surfaces I think it is almost redundant to put some over the horns. I use a special CF sheet we use in our company to manufacture roll scrapers from. It comes in long strips is about 4" wide and approx. 1.4mm thick. Super strong stuff. I use a small abrasive cutting wheel in my Dremel, cut out the rough shape and finish it on my belt sander. Then they are bundled together and drilled in a block at once. That way all holes are in the same position. Fairly easy and quick way and they look really cool[sm=shades_smile.gif]
