I've just built my second VIPER and no the tailplane on this model had been assembled wrong in the factory.....the central block sitting above the vee joint was not glued central to the joint and no matter how I screwed the thing together it wouldn't sit correct. I reshaped the actual seat in the fuselage with the Dremel and actually over cut. I had already concluded that the vee block above the joint determined the incidence so with microballoons and expoxy reformed the seat. I bolted the wing to the fuselage, slopped in the microb/ epoxy mix, inverted the whole thing on my bench then sat the tailplane into the tailplane seat and waited for it all to cure.......I now have some rather nice fillets at the fuselage/ veetail junction.....all easy and all realigned. How about the screw holes.....because now the holes don't lineup I simply cut the screws to about quarter length and epoxyied them into the holes. Nobody here knows that they are short and only I will ever need to undo the screws. I suspect this will give a far stronger rear end as I had glued the tailplane alsao to both the front and rear faces of the tailplane cut.
