I just put one togeather for a friend of mine. I also have the sixty size ultra stick which I have been flying for about eight months now.
I do alot of snap maneuvers with mine and have never had any problems with the tail or anything else for that matter.
But as the other guy said cut all covering away without scoring the wood so that you have wood to wood contact. Also I drill a few small holes into the wood on the underside of the fin/stab so that the epoxy goes deeper into the wood for extra strength.
And you are right about the vertical stab not being right at 90 degree's. You will need to cut or sand the socket that the stablizer goes into and use a tringle to set stablizer into place while epoxy dries.
Also if you have not mounted your Horzontal Stablizer into place yet. Use a drill bit to make small holes in the fuselage in the mounting area before you epoxy it into place, It will give it much more holding power than just epoxy on the surface of the wood.
Good luck, They fly Great!!
