I started off by trimming off the ears on the trim tab. (see later post for a problem I noticed)
I then decided I would try to use the ribs that came with the practice kit to build a little riblet for the inboard trim tab end and a 703 rib for the outboard trim tab rib......the one problem I ran into was that the rib from the practice kit was already matched drilled and I messed up trying to match drill from the rib to the skin.......New Rib Order!!!!
