I would have built the extension in place, as a piece of foam glued to the end, shaped using the existing airfoil, and then carbon-fibered in place, overlapping the existing stabilizer (after sanding to expose raw fiberglass) by something like 3"-4". T-88 isn't the first epoxy I'd have thought of for that job (the way I describe above), but given that it's already built, T-88 should work fine, as its thickness would help ensure all surfaces are in good contact. Rough it all up to ensure lots of "tooth", of course. Mark Langford ML at N56ML.com http://www.n56ml.com
