I dont understand what you mean by "shaped" The leading edge of both fin and stab are rounded, and the TE is square. Rudder and elevator are both rounded on the LE and TE. I just pinned the parts to the plans (with waxed paper over top) and just glued it, then sheeted with 1/32 balsa (or 1/16 I dont remember). Good luck on yours, you're in for a lot of sanding!! If you have any building questions, please look me up while everything is still fresh on my mind. Can't wait to fly it
